512Mbit (16Mx32bit) Mobile SDR Memory  
H55S5122DFR Series / H55S5132DFR Series  
DESCRIPTION  
The Hynix H55S5122DFR is suited for non-PC application which use the batteries such as PDAs, 2.5G and 3G cellular  
phones with internet access and multimedia capabilities, mini-notebook, hand-held PCs.  
The Hynix 512M Mobile SDRAM is 536,870,912-bit CMOS Mobile Synchronous DRAM(Mobile SDR), ideally suited for the  
main memory applications which requires large memory density and high bandwidth. It is organized as 4banks of  
4,194,304x32.  
Mobile SDRAM is a type of DRAM which operates in synchronization with input clock. The Hynix Mobile SDRAM latch  
each control signal at the rising edge of a basic input clock (CLK) and input/output data in synchronization with the  
input clock (CLK). The address lines are multiplexed with the Data Input/ Output signals on a multiplexed x32 Input/  
Output bus. All the commands are latched in synchronization with the rising edge of CLK.  
The Mobile SDRAMs provides for programmable read or write Burst length of Programmable burst lengths: 1, 2, 4, 8  
locations or full page. An AUTO PRECHARGE function may be enabled to provide a self-timed row precharge that is ini-  
tiated at the end of the burst access. The Mobile SDRAM uses an internal pipelined architecture to achieve high-speed  
operation. This architecture is compatible with the 2n rule of prefetch architectures, but it also allows the column  
address to be changed on every clock cycle to achieve a high-speed, fully random access. Precharging one bank while  
accessing one of the other three banks will hide the precharge cycles and provide seamless, high-speed, random-  
access operation.  
Read and write accesses to the Hynix Mobile SDRAMs are burst oriented;  
accesses start at a selected location and continue for a programmed number of locations in a programmed sequence.  
Accesses begin with the registration of an ACTIVE command, which is then followed by a READ or WRITE command.  
The address bits registered coincident with the ACTIVE command are used to select the bank and the row to be  
accessed. The address bits registered coincident with the READ or WRITE command are used to select the bank and  
the starting column location for the burst access. A burst of Read or Write cycles in progress can be terminated by a  
burst terminate command or can be interrupted and replaced by a new burst Read or Write command on any  
cycle(This pipelined design is not restricted by a 2N rule).  
The Hynix Mobile SDR also provides for special programmable options including Partial Array Self Refresh of full array,  
half array, quarter array Temperature Compensated Self Refresh of 45 or 85 degrees oC.  
The Hynix Mobile SDR has the special Low Power function of Auto TCSR(Temperature Compensated Self Refresh) to  
reduce self refresh current consumption. Since an internal temperature sensor is implanted, it enables to automatically  
adjust refresh rate according to temperature without external EMRS command.  
Deep Power Down Mode is a additional operating mode for Mobile SDR. This mode can achieve maximum power  
reduction by removing power to the memory array within each Mobile SDR. By using this feature, the system can cut  
off almost all DRAM power without adding the cost of a power switch and giving up mother-board power-line layout  
flexibility.  
All inputs are LV-CMOS compatible. Devices will have a VDD and VDDQ supply of 1.8V (nominal).

INFORMATION for Hynix KNOWN GOOD DIE  
With the advent of Multi-Chip package (MCPs), Package on Package (PoP) and system in a package (SiP) applications,  
customer demand for Known Good Die (KGD) has increased.  
Requirements for smaller form factors and higher memory densities are fueling the need for Wafer-level memory solu-  
tions due to their superior flexibility. Hynix Known Good Die (KGD) products can be used in packaging technologies  
such as systems-in-a-package (SIPs) and multi-chip packages (MCPs) to reduce the board area required, making them  
ideal for hand-held PCs, and many other portable digital applications.  
Hynix Mobile DRAM will be able to continue its constant effort of enabling the Advanced package products of all appli-  
cation customers.

Notes:  
1. Assume tR / tF (input rise and fall time) is 1ns. If tR & tF> 1ns, then [(tR+tF)/2-1]ns should be added to the parameter.  
2. Access time to be measured with input signals of 1V/ns edge rate, from 0.8V to 0.2V. If tR> 1ns, then (tR/2-0.5)ns  
should be added to the parameter.  
3. Output Load: 30pF+No termination  
AC high level input voltage / low level input voltage: 1.6 / 0.2V  
Input timing measurement reference level: 0.9V  
Transition time (input rise and fall time): 0.5ns

Notes:  
1. For the given current state CKE must be low in the previous cycle.  
2. When CKE has a low to high transition, the clock and other inputs are re-enabled asynchronously.  
When exiting power down mode, a NOP (or Device Deselect) command is required on the first positive edge of  
clock after CKE goes high.  
3. The address inputs depend on the command that is issued.  
4. The Precharge Power Down mode, the Self Refresh mode, and the Mode Register Set can only be entered  
from the all banks idle state.  
5. When CKE has a low to high transition, the clock and other inputs are re-enabled asynchronously.  
When exiting deep power down mode, a NOP (or Device Deselect) command is required on the first positive edge of  
clock after CKE goes high and is maintained for a minimum 200usec.

DESELECT  
The DESELECT function (CS = High) prevents new commands from being executed by the Mobile SDRAM, the Mobile  
SDRAM ignore command input at the clock. However, the internal status is held. The Mobile SDRAM is effectively dese-  
lected. Operations already in progress are not affected.  
NO OPERATION  
The NO OPERATION (NOP) command is used to perform a NOP to a Mobile SDRAM that is selected (CS = Low, RAS =  
CAS = WE = High). This command is not an execution command. However, the internal operations continue. This pre-  
vents unwanted commands from being registered during idle or wait states. Operations already in progress are not  
affected. (see to next figure)  
ACTIVE  
The Active command is used to activate a row in particular bank for a subsequent Read or Write access. The value of  
the BA0,BA1 inputs selects the bank, and the address provided on A0-A13(only for the 1KBytes page size. For the  
2KBytes page size, A0~A12 are provided) selects the row. This row remains active (or open) for accesses until a PRE-  
CHARGE command is issued to that bank. (see to next figure)

READ / WRITE COMMAND  
Before executing a read or write operation, the corresponding bank and the row address must be activated by the  
bank active (ACT) command. An interval of tRCD is required between the bank active command input and the follow-  
ing read/write command input.  
The READ command is used to initiate a Burst Read to an active row. The value of BA0 and BA1 selects the bank and  
address inputs select the starting column location.  
The value of A10 determines whether or not auto precharge is used. If auto-precharge is selected, the row being  
accessed will be precharged at the end of the read burst; if auto precharge is not selected, the row will remain open  
for subsequent access. The valid data-out elements will be available CAS latency after the READ command is issued.  
The WRITE command is used to initiate a Burst Write access to an active row. The value of BA0, BA1 selects the bank  
and address inputs select the starting column location.  
The value of A10 determines whether or not auto precharge is used. If auto-precharge is selected, the row being  
accessed will be precharged at the end of the write burst; if auto precharge is not selected, the row will remain open  
for subsequent access.  
When READ or WRITE command issues, the A0~A7 (column address) are provided if only 1KBytes page size. If the  
page size is 2KBytes, the A0~A8 (column address) are provided as shown below figure.

READ  
A read operation starts when a read command is input. Output buffer becomes Low-Z in the (/CAS Latency - 1)  
cycle after read command set. The SDRAM can perform a burst read operation.  
The burst length can be set to 1, 2, 4 and 8. The start address for a burst read is specified by the column address and  
the bank select address at the read command set cycle. In a read operation, data output starts after the number of  
clocks specified by the /CAS Latency. The /CAS Latency can be set to 2 or 3.  
When the burst length is 1, 2, 4 and 8 the DOUT buffer automatically becomes High-Z at the next clock after the suc-  
cessive burst-length data has been output.  
The /CAS latency and burst length must be specified at the mode register.

READ to READ  
Data from a read burst may be concatenated or truncated by a subsequent READ command. The first data from the  
new burst follows either the last element of a completed burst or the last desired element of a longer burst that is  
being truncated.  
When another read command is executed at the same ROW address of the same bank as the preceding read com-  
mand execution, the second read can be performed after an interval of no less than 1 clock. Even when the first com-  
mand is a burst read that is not yet finished, the data read by the second command will be valid.

Notes:  
1. Same bank, same ROW address: When the write command is executed at the same ROW address of the same bank as  
the preceding read command, the write command can be performed after an interval of no less than 1 clock.  
However, DQM must be set High so that the output buffer becomes High-Z before data input.  
2. Same bank, different ROW address: When the ROW address changes, consecutive write commands cannot be executed;  
it is necessary to separate the two commands with a precharge command and a bank active command.  
3. Different bank: When the bank changes, the write command can be performed after an interval of no less than 1 cycle, provided  
that the other bank is in the bank active state. However, DQM must be set High so that the output buffer becomes High-Z before  
data input.

READ to PRECHARGE  
Following the PRECHARGE command, a subsequent command to the same bank cannot be issued until tRP is met.  
Note that part of the row precharge time is hidden during the access of the last data element(s).  
In the case of a fixed-length burst being executed to completion, a PRECHARGE command issued at the optimum time  
(as described above) provides the same operation that would result from the same fixed-length burst with auto pre-  
charge.  
The disadvantage of the PRECHARGE command is that it requires that the command and address buses be available at  
the appropriate time to issue the command; the advantage of the PRECHARGE command is that it can be used to trun-  
cate fixed-length or full-page bursts.

Write  
Input data appearing on the data bus, is written to the memory array subject to the DM input logic level appearing  
coincident with the data. If a given DM signal is registered Low, the corresponding data will be written to the memory;  
if the DM signal is registered High, the corresponding data inputs will be ignored, and a write will not be executed to  
that byte / column location.  
During WRITE bursts, the first valid data-in element will be registered coincident with the WRITE command. Subse-  
quent data elements will be registered on each successive positive clock edge. Upon completion of a fixed-length  
burst, assuming no other commands have been initiated, the DQ will remain High-Z and any additional input data will  
be ignored. A full-page burst will continue until terminated.  
Data for any WRITE burst may be truncated with a subsequent WRITE command, and data for a fixed-length WRITE  
burst may be immediately followed by data for a WRITE command. The new WRITE command can be issued on any  
clock following the previous WRITE command, and the data provided coincident with the new command applies to the  
new command.

Basic Write timing parameters for Write Burst Operation  
Notes:  
1. Same bank, same ROW address: When another write command is executed at the same ROW address of the same bank as the  
preceding write command, the second write can be performed after an interval of no less than 1 clock. In the case of burst writes,  
the second write command has priority.  
2. Same bank, different ROW address: When the ROW address changes, consecutive write commands cannot be executed;  
it is necessary to separate the two write commands with a precharge command and a bank active command.  
3. Different bank: When the bank changes, the second write can be performed after an interval of no less than 1 clock,  
provided that the other bank is in the bank active state. In the case of burst write, the second write command has priority.

Data for any WRITE burst may be concatenated with or truncated with a subsequent WRITE command. In either case,  
a continuous flow of input data, can be maintained. The new WRITE command can be issued on any positive edge of  
the clock following the previous WRITE command. The first data-in element from the new burst is applied after either  
the last element of a completed burst or the last desired data element of a longer burst which is being truncated. The  
new WRITE command should be issued X cycles after the first WRITE command, where X equals the number of  
desired data-in element.

read command in the write cycle. The data of the read command (READ) is output after the lapse of the /CAS latency.  
The preceding write operation (WRIT) writes only the data input before the read command.  
The data bus must go into a high-impedance state at least one cycle before output of the latest data.  
Notes:  
1. Same bank, same ROW address: When the read command is executed at the same ROW address of the same bank  
as the preceding write command, the read command can be performed after an interval of no less than 1 clock.  
However, in the case of a burst write, data will continue to be written until one clock before the read command is  
executed.  
2. Same bank, different ROW address: When the ROW address changes, consecutive read commands cannot be  
executed; it is necessary to separate the two commands with a precharge command and a bank active command.  
3. Different bank: When the bank changes, the read command can be performed after an interval of no less than 1  
clock, provided that the other bank is in the bank active state. However, in the case of a burst write, data will  
continue to be written until one clock before the read command is executed (as in the case of the same bank  
and the same address).

WRITE to PRECHARGE  
Data for any WRITE burst may be followed by a subsequent PRECHARGE command to the same bank (provided Auto  
Precharge was not activated). When the precharge command is executed for the same bank as the write command  
that preceded it, the minimum interval between the two commands is 1 clock. However, if the burst write operation is  
unfinished, the input data must be masked by means of DQM for assurance of the clock defined by tDPL. To follow a  
WRITE without truncating the WRITE burst, tDPL should be met as shown in Fig.

The BURST TERMINATE command is used to truncate read bursts or write bursts (with auto precharge disabled). The

PRECHARGE  
The PRECHARGE command is used to deactivate the open row in a particular bank or the open row in all banks.  
Another command to the same bank (or banks) being precharged must not be issued until the precharge time (tRP) is  
completed.  
If one bank is to be precharged, the particular bank address needs to be specified. If all banks are to be precharged,  
A10 should be set high along with the PRECHARGE command. If A10 is high, BA0 and BA1 are ignored. A PRECHARGE  
command will be treated as a NOP if there is no open row in that bank, or if the previously open row is already in the  
process of precharging.

AUTO PRECHARGE  
Auto Precharge is a feature which performs the same individual bank precharge function as described above, but with-  
out requiring an explicit command.  
This is accomplished by using A10 (A10=high), to enable auto precharge in conjunction with a specific Read or Write  
command. This precharges the bank/row after the Read or Write burst is complete.  
Auto precharge is non persistent, so it should be enabled with a Read or Write command each time auto precharge is  
desired. Auto precharge ensures that a precharge is initiated at the earliest valid stage within a burst.  
The user must not issue another command to the same bank until the precharge time (tRP) is completed.

AUTO REFRESH AND SELF REFRESH  
Mobile SDRAM devices require a refresh of all rows in any rolling 64ms interval. Each refresh is generated in one of two  
ways: by an explicit AUTO REFRESH command, or by an internally timed event in SELF REFRESH mode:  
- AUTO REFRESH.  
This command is used during normal operation of the Mobile SDRAM. It is non persistent, so must be issued each time  
a refresh is required. The refresh addressing is generated by the internal refresh controller.The Mobile SDRAM requires  
AUTO REFRESH commands at an average periodic interval of tREF.  
To allow for improved efficiency in scheduling and switching between tasks, some flexibility in the absolute refresh  
interval is provided. A maximum of eight AUTO REFRESH commands can be posted to any given Mobile SDRMA, and  
the maximum absolute interval between any AUTO REFRESH command and the next AUTO REFRESH command is  
8*tREF.  
-SELF REFRESH.  
This state retains data in the Mobile SDRAM, even if the rest of the system is powered down. Note refresh interval tim-  
ing while in Self Refresh mode is scheduled internally in the Mobile SDRAM and may vary and may not meet tREF time.  
After executing a self-refresh command, the self-refresh operation continues while CKE is held Low. During self refresh  
operation, all ROW addresses are refreshed by the internal refresh timer. A self-refresh is terminated by a self-refresh  
exit command. Before and after self-refresh mode, execute auto-refresh to all refresh addresses in or within tREF  
(max.) period on the condition 1 and 2 below.  
1. Enter self-refresh mode within time as below* after either burst refresh or distributed refresh at equal interval to all  
refresh addresses are completed.  
2. Start burst refresh or distributed refresh at equal interval to all refresh addresses within time as below* after exiting  
from self-refresh mode.  
Note: tREF (max.) / refresh cycles.  
The use of SELF REFRESH mode introduces the possibility that an internally timed event can be missed when CKE is  
raised for exit from self refresh mode. Upon exit from SELF REFRESH an extra AUTO REFRESH command is recom-  
mended. In the self refresh mode, two additional power-saving options exist. They are Temperature Compensated Self  
Refresh and Partial Array Self Refresh and are described in the Extended Mode Register section.  
The Self Refresh command is used to retain cell data in the Mobile SDRAM. In the Self Refresh mode, the Mobile  
SDRAM operates refresh cycle asynchronously.  
The Self Refresh command is initiated like an Auto Refresh command except CKE is disabled(Low). The Mobile SDRAM  
can accomplish an special Self Refresh operation by the specific modes(PASR) programmed in extended mode regis-  
ters. The Mobile SDRAM can control the refresh rate automatically by the temperature value of Auto TCSR(Tempera-  
ture Compensated Self Refresh) to reduce self refresh current and select the memory array to be refreshed by the  
value of PASR(Partial Array Self Refresh). The Mobile SDRAM can reduce the self refresh current(IDD6) by using these  
two modes.

POWER DOWN  
Power down occurs if CKE is set low coincident with Device Deselect or NOP command and when no accesses are in  
progress. If power down occurs when all banks are idle, it is Precharge Power Down.  
If Power down occurs when one or more banks are Active, it is referred to as Active power down. The device cannot  
stay in this mode for longer than the refresh requirements of the device, without losing data. The power down state is  
exited by setting CKE high while issuing a Device Deselect or NOP command.  
If power-down occurs when all banks are idle, this mode is referred to as precharge power-down; if power-down  
occurs when there is a row active in any bank, this mode is referred to as active power-down. Entering power-down  
deactivates the input and output buffers, excluding CKE, for maximum power savings while in standby.  
DEEP POWER-DOWN  
The Deep Power-Down (DPD) mode enables very low standby currents. All internal voltage generators inside the  
Mobile SDRAM are stopped and all memory data is lost in this mode.  
All the information in the Mode Register and the Extended Mode Register is lost. Next Figure, DEEP POWER-DOWN  
COMMAND shows the DEEP POWER-DOWN command All banks must be in idle state with no activity on the data bus  
prior to entering the DPD mode. While in this state, CKE must be held in a constant low state.  
To exit the DPD mode, CKE is taken high after the clock is stable and NOP command must be maintained for at least  
200 us. After 200 us a complete re-initialization routing is required defined for the initialization sequence.

Power-up and Initialization  
Like a Synchronous DRAM, Low Power SDRAM(Mobile SDRAM) must be powered up and initialized in a predefined man-  
ner. Power must be applied to VDD and VDDQ(simultaneously). The clock signal must be started at the same time. After  
power up, an initial pause of 200 usec is required. And a precharge all command will be issued to the Mobile SDRAM.  
Then, 8 or more Auto refresh cycles will be provided. After the Auto refresh cycles are completed, a mode register  
set(MRS) command will be issued to program the specific mode of operation (Cas Latency, Burst length, etc.) And a  
extended mode register set command will be issued to program specific mode of self refresh operation(PASR). The fol-  
lowing these cycles, the Mobile SDRAM is ready for normal operation.  
Programming the registers  
Mode Register  
The mode register contains the specific mode of operation of the Mobile SDRAM. This register includes the selection of  
a burst length(1, 2, 4, 8, Full Page), a cas latency(2 or 3), a burst type. The mode register set must be done before any  
activate command after the power up sequence. Any contents of the mode register be altered by re-programming the  
mode register through the execution of mode register set command.  
Extended Mode Register  
The extended mode register contains the specific features of self refresh operation of the Mobile SDRAM. This register  
includes the selection of partial arrays to be refreshed(half array, quarter array, etc.). The extended mode register set  
must be done before any activate command after the power up sequence. Any contents of the mode register be altered  
by re-programming the mode register through the execution of extended mode register set command.  
Bank(Row) Active  
The Bank Active command is used to activate a row in a specified bank of the device. This command is initiated by  
activating CS, RAS and deasserting CAS, WE at the positive edge of the clock. The value on the BA1 and BA0 selects  
the bank, and the value on the A0-A13(or A12 which depends on page size) selects the row. This row remains active  
for column access until a precharge command is issued to that bank. Read and write operations can only be initiated  
on this activated bank after the minimum tRCD time is passed from the activate command.  
Read  
The READ command is used to initiate the burst read of data. This command is initiated by activating CS, CAS, and  
deasserting WE, RAS at the positive edge of the clock. BA1 and BA0 inputs select the bank, A8-A0 address inputs select  
the starting column location. The value on input A10 determines whether or not Auto Precharge is used. If Auto Pre-  
charge is selected the row being accessed will be precharged at the end of the READ burst; if Auto Precharge is not  
selected, the row will remain active for subsequent accesses.  
The length of burst and the CAS latency will be determined by the values programmed during the MRS command.  
Write  
The WRITE command is used to initiate the burst write of data. This command is initiated by activating CS, CAS, WE  
and deasserting RAS at the positive edge of the clock. BA1 and BA0 inputs select the bank, A8-A0 address inputs select  
the starting column location. The value on input A10 determines whether or not Auto Precharge is used.  
If Auto Precharge is selected the row being accessed will be precharged at the end of the WRITE burst; if Auto Pre-  
charge is not selected, the row will remain active for subsequent accesses.

H55S5122DFR Series / H55S5132DFR Series  
Precharge  
The Precharge command is used to close the open row in a particular bank or the open row in all banks. When the  
precharge command is issued with address A10, high, then all banks will be precharged, and If A10 is low, the open  
row in a particular bank will be precharged. The bank(s) will be available when the minimum tRP time is met after the  
precharge command is issued.  
Auto Precharge  
The Auto Precharge command is issued to close the open row in a particular bank after READ or WRITE operation. If  
A10 is high when a READ or WRITE command is issued, the READ or WRITE with Auto Precharge is initiated.  
Burst Termination  
The Burst Termination is used to terminate the burst operation. This function can be accomplished by asserting a Burst  
Stop command or a Precharge command during a burst READ or WRITE operation. The Precharge command interrupts  
a burst cycle and close the active bank, and the Burst Stop command terminates the existing burst operation leave the  
bank open.  
Data Mask  
The Data Mask command is used to mask READ or WRITE data. During a READ operation, When this command is is-  
sued, data outputs are disabled and become high impedance after two clock delay. During a WRITE operation, When  
this command is issued, data inputs can't be written with no clock delay.  
If data mask is initiated by asserting low on DQM during the read cycle, the data outputs are enabled.  
If DQM is asserted to High. the data outputs are masked (disabled) and become Hi-Z state after 2 cycle later. During  
the write cycle, DQM mask data input with zero latency

Clock Suspend  
The Clock Suspend command is used to suspend the internal clock of Mobile SDRAM. The clock suspend operation stops  
transmission of the clock to the internal circuits of the device during burst transfer of data to stop the operation of the  
device. During normal access mode, CKE is keeping High. When CKE is low, it freezes the internal clock and extends  
data Read and Write operations. (See examples in next Figures)

Power Down  
The Power Down command is used to reduce stand-by current. Before this command is issued, all banks must be pre-  
charged and tRP must be passed after a precharge command. Once the Power Down command is initiated by keeping  
CKE low, all of the input buffer except CKE are gated off.  
Auto Refresh  
The Auto Refresh command is used during normal operation and is similar to CBR refresh in Conventional DRAMs.  
This command must be issued each time a refresh is required. When an Auto Refresh command is issued, the address  
bits is ''Don't care'', because the specific address bits is generated by internal refresh address counter.  
Self Refresh  
The Self Refresh command is used to retain cell data in the Mobile SDRAM. In the Self Refresh mode, the Mobile SDRAM  
operates refresh cycle asynchronously.  
The Self Refresh command is initiated like an Auto Refresh command except CKE is disabled(Low). The Mobile SDRAM  
can accomplish an special Self Refresh operation by the specific modes(PASR) programmed in extended mode registers.  
The Mobile SDRAM can control the refresh rate automatically by the temperature value of Auto TCSR(Temperature  
Compensated Self Refresh) to reduce self refresh current and select the memory array to be refreshed by the value of  
PASR(Partial Array Self Refresh). The Mobile SDRAM can reduce the self refresh current(IDD6) by using these two  
modes.  
Deep Power Down  
The Deep Power Down Mode is used to achieve maximum power reduction by cutting the power of the whole memory  
array of the devices.
