2.1
DiskOnChip DIMM Plus is a member of M-Systems’ DiskOnChip product series. DiskOnChip DIMM Plus
provides a complete, easily integrated flash disk for highly reliable data and code storage. DiskOnChip DIMM Plus
also offers advanced protection and security-enabling features for both data and code storage. Available in 144-pin
SO-DIMM form factor, it is optimized for applications such as connected devices, set-top boxes, thin clients,
network computers, telecommunication and embedded systems.
DiskOnChip DIMM Plus protection and security-enabling features offer a number of benefits. Two write and read-
protected partitions, with both software and hardware-based protection, can be configured independently for
maximum design flexibility. The Unique ID (UID) identifies each flash device, 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.
DiskOnChip DIMM Plus is based on Toshiba’s cutting-edge 0.16µ NAND flash technology. This technology
enables DiskOnChip DIMM 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.
Using 16-bit internal flash access, it features unrivaled write and read performance: 1.5MB/sec write and 3 MB/sec
read.
M-Systems’ patented TrueFFS software technology fully emulates a hard disk to manage the files stored on
DiskOnChip DIMM 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 VxWorks, Windows CE, Windows XP, Linux, pSOS, QNX. Customers developing for target platforms
not supported by TrueFFS binary drivers can use the TrueFFS Software Development Kit (SDK). For customized
boot solutions, M-Systems provides the Boot SDK.
DiskOnChip DIMM Plus is a cost-effective solution for code storage as well as data storage. A Programmable Boot
Block with eXecute In Place (XIP) capability can store boot code, replacing the boot ROM to function as the only
non-volatile memory on board. This reduces hardware expenditures and board real-estate. M-Systems’ Download
Engine (DE) is an automatic bootstrap mechanism that expands the functionality of the physical 1KB programmable
boot block to enable system initialization from DiskOnChip.
DiskOnChip DIMM Plus is available in capacities ranging from 32Mbyte (256Mbit) to 128Mbyte (1,024Mbit). The
same pinout is retained for all capacities, enabling an easy upgrade path and maximum design flexibility.
