M-Systems Ltd., (sometimes spelled msystems[3]) was a Nasdaq-listed Israeli producer of flash memory storage products founded in 1989 by Dov Moran and Aryeh Mergi, [1] [2] based in Kfar Saba, Israel.

The device was supplied as a module in a 32-pin dual in-line package (DIP) with a pinout and electrical interface compatible with a standard JEDEC socket for memory chips.

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.

This software and initially the Flash memory from Toshiba were combined to form the first solid state storage product called DiskOnChip.

Rick Iorillo lead the development and design efforts in the U.S. and established the first distributor base for the sale of the 28 pin DIP with Ampro being the first customer in the U.S.

[4] IBM was the first to market USB flash drives in North America, purchasing them from M-Systems and selling them under the IBM-brand label.

[4] M-systems was competing in the flash market with SanDisk, but the introduction of the USB drive made a cooperative environment more financially advantageous.

In 2004, the two companies entered into a strategic agreement with cross licensing of patents to develop new USB drive platforms introduced in 2005.
