Description
capacitive loading to the system bus, but adds one cycle to
the SDRAM timing. Decoupling capacitors are mounted on
the PCB board. The DIMMs feature serial presence detect
based on a serial E

protocol. The first 128 bytes are programmed with
configuration data and the second 128 bytes are available to
the customer.
The QIMONDA HYS72T64301HP–[3S/3.7]–A module family
are Very Low Profile (VLP) Registered DIMM (RDIMM with
parity) with 18.30 mm height based on DDR2 technology.
DIMMs are available as ECC modules in 64M x 72
(512 MByte) organization and density, intended for mounting
into 240-Pin connector sockets.
The memory array is designed with 256-Mbit Double-Data-
Rate-Two (DDR2) Synchronous DRAMs. All control and
address signals are re-driven on the DIMM using register
devices and a PLL for the clock distribution. This reduces

1) All Product Types end with a place code, designating the silicon die revision. Example: HYS72T64301HP–3.7–A, indicating Rev. “A” dies
are used for DDR2 SDRAM components. For all QIMONDA DDR2 module and component nomenclature see
of this data sheet.
2) The Compliance Code is printed on the module label and describes the speed grade, for example “PC2–4200P–444–12–U0”, where 4200P
means Very Low Profile Registered DIMM modules with 4.26 GB/sec Module Bandwidth and “444-12” means Column Address Strobe
(CAS) latency = 4, Row Column Delay (RCD) latency = 4 and Row Precharge (RP) latency = 4 using the latest JEDEC SPD Revision 1.2
