Product Description
iDiskOnChip complements the DiskOnChip product line, offering full IDE capabilities, high
performance, a built-in ECC system and flexible design options. It can be used in any system with
an IDE bus and can work with any operating system, since the driver is handled at the BIOS level.
iDiskOnChip is based on NAND flash technology. This technology is superior in its data storage
characteristics, featuring the industry’s highest write and erase performance, as well as the highest
burst read/write transfer rate. Additionally, NAND flash technology is known for its high density
and small die size, with the related cost and real estate benefits. Data integrity is guaranteed through
embedded error detection and error correction code (EDC/ECC) that automatically detects and
corrects data errors. An on-chip ECC unit generates the required code bytes for error detection and
correction of up to 2 bits per 512-byte data sector. Code-byte generation during write operations, as
well as error detection during read operation, is implemented on the fly without performance
degradation.
iDiskOnChip is ergonomically designed for easy installation and ready-to-run operation. Available
in 40-pin and 44-pin connector packages, iDiskOnChip fits easily into any platform with an IDE
connector.
The horizontal version is provided in both left and right orientations, giving maximum flexibility for
insertion to the host platform.
iDiskOnChip is available in capacities ranging from 16MB to 1536MB, making the upgrade path
simple and fast.
