uDiskOnChip (uDOC) is the ideal data storage device in any USB-capable system, capitalizing on
M-Systems’ expertise in three fields: The USB interface (based on its USB flash drive), flash drives
for the embedded market (based on the DiskOnChip product line), and security (based on patented
algorithms).
uDiskOnChip offers the speed and ease of the USB interface. uDiskOnChip can work with any
operating system that supports USB Mass Storage Class devices, such as Windows XP Embedded,
Windows CE, Linux, and others.
M-Systems’ patented TrueFFS flash management technology, which fully emulates a hard disk in
DiskOnChip products, is embedded in the uDiskOnChip firmware to streamline integration efforts.
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. Data integrity is guaranteed through an embedded
4-bit error detection and error correction code algorithm that automatically detects and corrects data
errors. The EDC/ECC algorithm is based on a combination of Hamming and BCH code.
uDiskOnChip provides data protection in hardware, utilizing RSA with a 64-byte key. This feature
is enabled by the SuperMAP cryptographic engine developed by M-Systems’ Fortress division and
used successfully in thousands of smartcards.
uDiskOnChip is based on Single Level Cell (SLC) NAND flash technology. This technology is
superior in its data storage characteristics, featuring the industry’s highest performance.
Additionally, NAND flash technology is known for its high density and small die size, with the
related cost and real estate benefits. Multi-Level Cell (MLC) NAND is planned for use in the
next-generation product, enabling further cost benefits.
uDiskOnChip is available in capacities ranging from 32MB to 2GB with a fast and simple upgrade
path. It fits easily into any platform with an embedded USB connector, and can be secured firmly
into place for enhanced ruggedness.
