iNAND is an Embedded Flash Drive (EFD) designed fo r mobile handsets and consumer electronic
devices. iNAND is a hybrid device combining an embedded thin flash controller and standard MLC
NAND flash memory, with an industry standard e.MMC 4.41
interface.
Empowered with a new e.MMC4.41 feature set such as Boot and RPMB partitions, HPI,
Background Operations and HW Reset the iNAND e.MMC is the optimal device for reliable code
and data storage.
Designed specifically for mobile multimedia applications, iNAND is the most mature on board
SD/MMC device since 2005, providing mass storage of up to 32GB in JEDEC compatible form
factors, with low power consumption and high performance - an ideal solution for multimedia
handsets of 2.5G, 3G, 3.5G and 4G.
In addition to the high reliability and high system performance offered by the current iNAND
family of products, iNAND offers plug-and-pl ay integration and support for multiple NAND
technology transitions, as well as features such as advanced power management scheme.
iNAND uses advanced Multi-Level Cell (MLC) NAN D flash technology, enhanced by SanDisk’s
embedded flash management software runni ng as firmware on the flash controller.
iNAND architecture and embedded firmware fully em ulates a hard disk to the host processor,
enabling read/write operations that are identical to a standard, sector-based hard drive. In addition,
SanDisk firmware employs patented methods, su ch as virtual mapping, dynamic and static wear-leveling, and automatic block management to ensu re high data reliability and maximize flash life
expectancy.
SanDisk iNAND provides up to 32GB of memory for use in mass storage appl ications. In addition
to the mass-storage-specific flash memory chip, iNAND includes an intelligent controller, which
manages interface protocols, data storage and retrieval, error co rrection code (ECC) algorithms,
defect handling and diagnostics, power management and clock control.

iNAND enables multimedia driven applications such as music, photo, video, TV, GPS, games,
email, office and other applications.
The breakthrough in performance and design makes iNAND the ideal solution for mobile handset
vendors, portable navigation and Automotive Infotainment vendors who require easy integration,
fast time to market and high-capacity.
