flash disk with mlc nand and m-systems’ x2 technology
data sheet, november 2005
highlights small form factors:
th 69-ball fbga 9x12 mm package
diskonchip g4 is m-systems”” 4 generation of
the diskonchip family of products. based on enhanced performance by implementation
multi-level cell (mlc) nand, utilizing of:
toshiba’s 90nm mlc nand large block dma support
flash technology and x2 technology from m- multiburst operation
systems, it is one of the industry’s most unrivaled data integrity with a robust error
efficient storage solutions. mlc nand flash detection code/error correction code
technology provides the smallest die size by (edc/ecc) tailored for mlc nand flash
storing 2 bits of information in a single memory technology
cell. x2 technology enables mlc nand to maximized flash endurance with trueffs(r)
achieve highly reliable, high-performance data 6.3.2 (and higher)
and code storage with a specially designed error
support for major operating systems (oss),
detection and correction mechanism, optimized
including symbian os, microsoft windows
file management, and proprietary algorithms for
mobile, palm os, nucleus, linux, ose,
enhanced performance.
windows ce, and more.
further cost benefits derive from the
compatible with major cpus, including
cost-effective architecture of diskonchip g4,
ti omap, ti dbb, intel xscale, infinion,
which includes a boot block that can replace
egold and sgold, adi 652x, freescale
expensive nor flash, and incorporates both the
mx, and qualcomm msmxxxx.
