Mobile DiskOnChip Plus 16/32MB is a member of M-Systems’ DiskOnChip product series. It is a
based on a single die (16MB) or dual die (32MB) with an embedded flash controller and flash
memory, providing a complete, easily integrated flash disk for highly reliable data storage. Mobile
DiskOnChip Plus also offers advanced features for hardware-protected data and code and security-
enabling features for both data and code storage. With superior read and write performance, small
size and low power consumption, it is optimized for the high-end handset, multimedia handset and
PDA markets. These markets require fast read and write rates, minimum weight and space, and low
power consumption to support the large and growing pool of data-rich applications.
Mobile DiskOnChip Plus protection and security features offer unique benefits. Two write- and
read-protected partitions, with both software- and hardware-based protection, can be configured
independently for maximum design flexibility. The 16-byte Unique ID (UID) identifies each flash
device, used with security and authentication applications, eliminating the need for a separate ID
device (i.e. EEPROM) on the motherboard. The user-configurable One Time Programmable (OTP)
area, written to once and then locked to prevent data and code from being altered, is ideal for
storing customer and product-specific information. In addition, the Bad Block Table is hardware
protected, ensuring that it will not be damaged or accidentally changed to ensure maximum
reliability.
Mobile DiskOnChip Plus devices have a simple SRAM-like interface, for easy integration. It can
also be configured to work with a multiplexed interface. Multiplexing data and address lines can
save board space, reduce RF noise effects, and more.
Mobile DiskOnChip Plus is based on Toshiba’s 0.16 micron NAND flash technology. This
technology enables Mobile DiskOnChip Plus to provide unmatched physical and performance-
related benefits. It has the highest flash density in the smallest die size available on the market, for
the best cost structure and the smallest real estate. Mobile DiskOnChip Plus devices use 8-bit
internal flash access, featuring unrivaled write and read performance.
Mobile DiskOnChip Plus is a cost-effective solution for code storage as well as data storage. A
Programmable Boot Block with eXecute In Place (XIP) functionality can store boot code, replacing
the boot ROM to function as the only non-volatile memory on board. The Programmable Boot
Block is 1KB for 16MB devices, and 2KB for 32MB devices. This reduces hardware expenditures
and board real estate. M-Systems’ Download Engine (DE) is an automatic bootstrap mechanism
that expands the functionality of the Programmable Boot Block to enable CPU and platform
initialization directly from Mobile DiskOnChip Plus.
M-Systems’ patented TrueFFS software technology fully emulates a hard disk to manage the files
stored on Mobile DiskOnChip Plus. This transparent file system management enables read/write
operations that are identical to a standard, sector-based hard disk. In addition, TrueFFS employs
various patented methods, such as dynamic virtual mapping, dynamic and static wear-leveling, and
automatic bad-block management to ensure high data reliability and to maximize flash lifetime.
TrueFFS binary drivers are available for a wide range of popular OSs, including Symbian OS,
