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 cutting-edge 0.16 µ 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, Pocket PC, Smartphone, Windows CE/.NET, OSE, Nucleus, and Linux. Customers developing for
target platforms not supported by TrueFFS binary drivers can use the TrueFFS Software Development Kit (SDK)
developer guide. For customized boot solutions, M-Systems provides the DiskOnChip Boot Software Development
Kit (BDK) developer guide.
Mobile DiskOnChip Plus is designed for compatibility and easy scalability. All capacities of Mobile DiskOnChip
Plus have the same ballout and are interchangeable. Greater capacities may easily be obtained by cascading up to
four 16MB devices or two 32MB devices with no additional glue logic. This upgrade path provides a flash disk of
up to 64MB (512Mb), while remaining totally transparent to the file system and user.
