2.1
DiskOnChip Millennium Plus is a member of M-Systems’ DiskOnChip product series. A single die (16/32MB) or
dual die (64MB) with embedded flash controller and flash memory, DiskOnChip Millennium Plus provides a
complete, easily integrated flash disk for highly reliable data and code storage. DiskOnChip Millennium Plus also
offers advanced features for hardware-protected data and code and security-enabling features for both data and code
storage. Available in two form factors, a 48-pin Thin Small Outline Package (TSOP-I) and a 69-ball Ball Grid Array
(BGA), and in capacities of 16MB (128Mb), 32MB (256Mb) and 64MB (512Mb), DiskOnChip Millennium Plus is
optimized for applications that require data and code storage, the industry’s highest reliability, exceptional
performance and minimum size. These include set-top boxes (STBs), handsets, personal digital assistants (PDAs),
thin clients, telecommunication applications and embedded systems.
DiskOnChip Millennium 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 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.
DiskOnChip Millennium Plus devices have a simple SRAM-like interface, for easy integration. DiskOnChip
Millennium Plus 16MB devices 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.
DiskOnChip Millennium Plus is based on Toshiba’s cutting-edge 0.16 µ NAND flash technology. This technology
enables DiskOnChip Millennium 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. DiskOnChip Millennium Plus 32/64MB devices use 16-bit internal flash access, featuring unrivaled write and
read performance.
M-Systems’ patented TrueFFS software technology fully emulates a hard disk to manage the files stored on
DiskOnChip Millennium 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, VxWorks, Windows CE/.NET, Linux, and 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 Software Development Kit (BDK).
DiskOnChip Millennium 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. The Programmable
Boot Block for 16/32MB devices is 1KB in size, and for 64MB devices it is 2KB in size. 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 DiskOnChip Millennium Plus.
DiskOnChip Millennium Plus is designed for compatibility and easy scalability. All capacities are drop-in
replacements for the same package, either TSOP-I or BGA. Greater capacities may easily be obtained by cascading
up to four devices with no additional glue logic. This upgrade path provides a flash disk of up to 128MB (1Gb),
while remaining totally transparent to the file system and user.
