M-Systems
M-Systems Ltd., was a Nasdaq-listed Israeli producer of flash memory storage products founded in 1989 by Dov Moran and Aryeh Mergi, based in Kfar Saba, Israel. They were best known for developing and patenting the first flash drive, marketed in 1995 as DiskOnChip, and the first USB flash drive, marketed in 2000 as DiskOnKey. They also created the patented True Flash Filing System which presented the flash memory as a disk drive to the computer. They also produced flash solid state drives for PATA, SATA, SCSI and SAS interfaces. After 17 years of business, they were acquired by their prior competitor, SanDisk, in 2006.
The DiskOnChip was developed at the R&D Center established by M-Systems called EUROM. Rick Iorillo, Rony Levy and David Deitcher were the individuals that worked on the development and marketing of the first 2 MB DOC. This product went on to receive the Most Innovative Award from EDN in 1995 and later went on to become the Flash Drive and DiskOnKey.
DiskOnKey
DiskOnKey was a small Flash memory device encased in a plastic enclosure with an integrated flash controller that connected to the USB port on a computer. It required no separate power or device drivers from the computer if running Windows 2000, or Windows ME; it was a true plug and play device. In Windows 98 it required a driver which was supplied on a CD-ROM. The computer saw the device as a hard disk drive and it came in capacities of 8, 16, and 32 MB. It was marketed as a hard disk on a keychain. It had an integrated LED which indicated when the device was reading or writing data to prevent premature removal from the computer. The performance was about 10 times faster than writing data to a floppy drive.DiskOnChip
The DiskOnChip product line became popular because they could easily be integrated into small embedded applications. The device was supplied as a module in a 32-pin dual in-line package with a pinout and electrical interface compatible with a standard JEDEC socket for memory chips. It employed a memory-mapped interface with an 8 KB window for models of all capacities. Internally, a DoC module contained a controller that implemented ECC, bad block re-mapping and wear leveling functions that were used to implement a file system, TrueFFS, for which the company provided software development kits.Some time after SanDisk acquired M-Systems, they announced the end-of-life for the DiskOnChip 2000 product line in early 2007, suggesting customers migrate to the uDOC product, CompactFlash, or SecureDigital cards, all of which are not directly compatible, requiring interface redesign. The subsidiary of M-Systems called EUROM was established to design, build and sell the DOC to the U.S. and Asian embedded computer distributors. The first customer for the DOC was Ampro. David Feldman, President of Ampro and Rick Iorillo, President of EUROM U.S. completed the first deal with IBM to supply 2MB embedded flash drives for recording transportation data on public buses in South America.
