1. INTRODUCTION

iNAND is an Embedded Flash Drive (EFD) designed for 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

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-play 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) NAND flash technology, enhanced by SanDisk‟s

embedded flash management software running as firmware on the flash controller.

iNAND architecture and embedded firmware fully emulates 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, such as virtual mapping, dynamic and static wear-

leveling, and automatic block management to ensure high data reliability and maximize flash life

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.

iNAND optimized architecture 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

iNAND device with another of a newer generation requires virtually no changes to the host. This

makes iNAND the perfect solution for platforms and reference designs, as it allows for the
