IGHLIGHTS
mDOC H3 is an Embedded Flash Drive (EFD)
designed for mobile handsets and consumer
electronics devices. mDOC H3 is the new
generation of the successful msystems’ mDOC
product family, enabling tens of millions of
handsets and other mobile devices since the
year 2000.
mDOC H3 is a hybrid device combining an
embedded thin flash controller and standard
flash memory.
In addition to the high reliability and high
system performance offered by the current
mDOC family of products, mDOC H3 offers
plug-and-play integration, support for multiple
NAND technologies and more features such as
advanced power management schemes.
mDOC H3 uses the most advanced Multi-
Level Cell (MLC) and binary (SLC) NAND
flash technologies, enhanced by msystems’
proprietary TrueFFS embedded flash
management software running as firmware on
the flash controller.
The breakthrough in performance, size, cost
and design makes mDOC H3 the ideal solution
for mobile handsets and consumer electronics
manufacturers who require easy integration,
fast time to market, high-capacity, small form
factor, high-performance and most importantly,
high reliable storage.
mDOC H3 enables multimedia driven
applications such as music, photo, video, TV,
GPS, games, email, office and other
applications.

mDOC H3 Embedded Flash Drive
Embedded TrueFFS enables mDOC H3 to
fully emulate a hard disk to the host processor,
enabling read/write operations that are
identical to a standard, sector-based hard drive.
In addition, Embedded TrueFFS employs
patented methods, such as virtual mapping,
dynamic and static wear-leveling, and
automatic block management to ensure high
data reliability and maximize flash life
expectancy.
Furthermore, it provides performance
enhancements such as multi-plane operations,
DMA support, Burst operation and Dual Data
RAM buffering.
mDOC H3 extended features are enabled by a
small driver that runs on the host side, called
DOC driver. DOC driver provides the host OS
with a standard Block Device interface. The
combination of Embedded TrueFFS and DOC
driver enables a practically Plug & Play
integration in the system.

UPPORT
mDOC H3 with Embedded TrueFFS enables
access to the most advanced binary SLC
NAND and MLC NAND flash technology,
making mDOC H3 the only multi-sourced and
multi-technology EFD.
Embedded TrueFFS overcomes SLC and MLC
NAND-related error patterns by using a robust
error detection and correction (EDC/ECC)
mechanism.
mDOC H3 optimized architecture with
Embedded TrueFFS guarantees high reliability
and high system performance for whatever
flash technology or density utilized.

NTEGRATION
mDOC H3 optimized architecture with
Embedded TrueFFS eliminates the need for
complicated software integration and testing
processes and enables a practically plug-and-
play integration in the system.
The replacement of one mDOC H3 device with
another, of a newer generation, requires
virtually no changes to the host. This makes
mDOC H3 the perfect solution for platforms
and reference designs, as it allows for the
utilization of more advanced NAND Flash
technology with minimal integration or
qualification efforts.
Embedded TrueFFS running from mDOC H3
means there is no need to modify and re-
qualify the flash management software on the
host system, or update mass production tools.
