2.1
Mobile DiskOnChip G3 is the latest addition to M-Systems’ DiskOnChip product family. Mobile
DiskOnChip G3, packed in the smallest available FBGA package with 512Mb (64MB) capacity, is
a single-die device with an embedded thin flash controller and flash memory. It uses Toshiba’s
cutting-edge, 0.13 µ NAND-based Multi-Level Cell (MLC) flash technology, enhanced by
M-Systems’ proprietary x2 technology. A dual-die device is available with single chip capacity of
1Gb (128MB).
MLC NAND technology enables two bits of data to be stored on a single cell, cutting in half the
physical die size. M-Systems’ proprietary x2 technology overcomes MLC-related error patterns and
slow transfer rates by using a robust error detection and correction (EDC/ECC) mechanism.
Furthermore, it provides performance enhancement with multi-plane operation, DMA support, turbo
operation and MultiBurst operation. The combination of MLC and x2 technology results in a low-
cost, minimal-sized flash disk that achieves unsurpassed reliability levels and enhanced
performance.
This breakthrough in performance, size and cost makes Mobile DiskOnChip G3 the ideal solution
for mobile product manufacturers who require high-capacity, small size, high-performance, and
above all, high-reliability storage to enable applications such as enhanced Multimedia Messaging
Service (MMS), gaming, video and Personal Information Management (PIM) on mobile handsets
and Personal Digital Assistants (PDAs).
As with the Mobile DiskOnChip Plus family (G2), Mobile DiskOnChip G3 content protection and
security-enabling features offer several 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, eliminating the need for a
separate ID device on the motherboard. The 6KB 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.
Mobile DiskOnChip G3 512Mb has a 2KB Programmable Boot Block (4KB for Mobile
DiskOnChip G3 1Gb). This block provides eXecute In Place (XIP) functionality, enabling Mobile
DiskOnChip G3 to replace the boot device and function as the only non-volatile memory device on-
board. Eliminating the need for an additional boot device reduces hardware expenditures, board real
estate, programming time, and logistics.
M-Systems’ patented TrueFFS software technology fully emulates a hard disk to manage the files
stored on Mobile DiskOnChip G3. This transparent file system management enables read/write
operations that are identical to a standard, sector-based hard disk. In addition, TrueFFS employs
patented methods, such as virtual mapping, dynamic and static wear-leveling, and automatic block
management to ensure high data reliability and to maximize flash life expectancy.
