SanDisk was founded in 1988 by Eli Harari, Sanjay Mehrotra, and Jack Yuan, incorporated at the time as SunDisk.[3] SanDisk co-founder Eli Harari developed the Floating Gate EEPROM which proved the practicality, reliability and endurance of semiconductor-based data storage.[4]
In 1991 SanDisk produced the first flash based SSD in a 2.5-inch hard disk drive form factor for IBM with a 20 MB capacity priced at about $1000.[5]
On May 10, 2000, the Toshiba Corporation of Japan and the SanDisk Corporation said that they would jointly form a new semiconductor company to produce advanced flash memory, primarily for digital cameras.[6]
SanDisk was acquired by hard disk drive manufacturer Western Digital on May 12, 2016 in a US$19 billion deal.[7][8] Since the acquisition, SanDisk has been losing market share.
