High-Reliability SD Memory Cards
The MMGB/MUGB series are SD/microSD cards with high level of
high-speed performance, data reliability, storage lifespan, and data security.
These series feature high-speed access that is compatible with CLASS10,
as well as 16 bit ECC, and realizes high data reliability. Using technology
developed for NAND type flash memory controllers, CF cards, and SSDs, a
proprietary algorithm reduces the risk of collateral data errors such as
corruption of data other than the data being written if power is interrupted
when writing data. These SD/microSD cards are ideal for industrial use.
The lifespan of SD cards are also improved drastically. These SD cards are
equipped with highly reliable Single Level Cell (SLC) NAND-type flash
memory, instead of Multi Level Cell (MLC) type NAND flash memory such as
Triple Level Cell (TLC) type NAND flash memory with low endurance, which
is generally used in consumer equipment area. In addition, it is equipped
with advanced writing dispersing mechanism by the all area global static
wear leveling algorithm to achieve the industry's highest class storage
lifespan, which is enough also for industrial area, in which they are used for
a long term with high frequency.
At the same time, SD card life monitor and diagnose software with rewriting
lifespan monitor function, “TDK SMART” is included, which was requested
frequently by customers who employed CF cards or SSD. The number of
programming (erasing) times of all memory blocks can be retrieved as
SMART information, which makes it easy to figure out a good timing for
maintenance and module replacement.

MAIN APPLICATIONS
FEATURES
1. Equipped with high-speed and highly-durable SLC NAND type Flash Memory.
2. Compatible with SDA Specification ver. 2.0. (*1)
● Thin-client computers, tablet computers, SATA RAID SSD installations, Data
servers, Enterprise servers, embedded cloud systems and other IT equipment for
cloud computing systems
3. Compatible with SDHC Class10 (more than 4 GB, less than 2 GB is SD
● Multi-function printers (MFPs), commercial-use projectors, telephone conferencing
systems, electronic blackboards and other office automation equipment
Class6).
Realizes high-speed access: 19 MByte/sec read access, 15 MByte/sec write
access. (*2)
● Karaoke on demand systems, arcade games and other amusement equipment
● Digital signage, electronic billboards, electronic point-of-purchase (POP) displays
4. Support SD command Class 0,2,4,5,7,8,10.
and other advertising display equipment
5. Equipped with 16 bits/KByte ECC. These series include the powerful ECC
ability of more than double of 4 bits, 8 bits/1 KByte ECC that is required by the
equipped SLC NAND type flash memory.
● Semiconductor manufacturing equipment, NC machine tools, sequencers,
programmable logic controllers, panel computers, embedded CPU boards and
other factory automation equipment
6. Equipped with a global static wear leveling algorithm. This algorithm counts
the number of times each memory block is erased (programmed) and
replaces blocks uniformly, which drastically improves the lifespan of the
installed flash memory.
● Automated ticket gates, automated ticket vending machines, commuter pass
vending machines, train movement management systems, automated air ticket
vending machines, automated check-in systems and other railway and transporta-
tion services equipment
The 8 GB type for example supports approximately 1.5 billion erase cycles.
Even at a rate of 5 erases per second, this equates to an expected service life
of 10 years. (*3)
● Cash registers and other point-of-sales (POS) equipment, convenience store and
kiosk terminals, ATMs and other banking terminals
7. TDK SMART life monitor software is included. Since the remained lifespan of
the SD cards/microSD cards is controlled easily, maintenance such as
knowing accurate lifespan and the appropriate timing of replacement.
● Diagnostic imaging systems, blood analysis equipment, medical PCs, electronic
patient records systems, DNA microarray systems, automatic biochemistry
analyzers, remote medical care devices, automated care devices and other
medical equipment and data analy
8. A dedicated FAE (Field Application Engineer) registration system provides fast
and reliable solutions such as for system compatibility verification and
customizing.
● Base station equipment for 4th generation (4G) mobile data communication
systems such as LTE-Advanced/WiMAX2 , data broadcasting system supporting
digital broadcasting and other communications and broadcasting equipment and
information system devices
9. Complies with RoHS directives. The components, lead terminals, etc. are all
free from hazardous substances prohibited by the RoHS Directives of the EU
(European Union).
● Smart electricity meters, power grid infrastructure equipment, automated power
equipment control systems, energy management systems, building air condition-
ing systems and other smart grid equipment
(*1) This is a standard defined by the SD Card Association.
(*2) Dependent on flash memory connection configuration and system environment.
(*3) This applies to a product equipped with an SLC flash memory with a structure of
4 KByte/page.
● Biometric authentication systems, entry/exit control systems, security terminals for
surveillance cameras and other security equipment
● Earthquake emergency information systems, household fire detectors and other
disaster prevention related equipment
● Car navigation systems, portable navigation devices (PND), Digital tachographs,
data logger, drive recorders, rear-view monitors and other automotive equipment
●
Complies with RoHS directives:
This means that, in conformity with EU Directive 2011/65/EU, lead, cadmium, mercury, hexavalent chromium, and specific bromine-based flame retardants, PBB and PBDE, have not been
used, except for exempted applications.
