SanDisk co-founder Eli Harari developed the Floating Gate EEPROM which proved the practicality, reliability and endurance of semiconductor-based data storage. [7] In 1991, SanDisk produced the first flash-based solid-state drive (SSD) in a 2.5-inch hard disk drive form factor for IBM with a 20 MB capacity priced at about $1,000. [8]
The first EEPROM that used Fowler-Nordheim tunnelling to erase data was invented by Bernward and patented by Siemens in 1974. [24] In February 1977, Israeli-American Eliyahou Harari at Hughes Aircraft Company patented in the US a modern EEPROM technology, based on Fowler-Nordheim tunnelling through a thin silicon dioxide layer between the floating-gate and the wafer.
Unveiled in 1997 by SanDisk and Siemens, [1] MMC is based on a surface-contact low-pin-count serial interface using a single memory stack substrate assembly, and is therefore much smaller than earlier systems based on high-pin-count parallel interfaces using traditional surface-mount assembly such as CompactFlash.
Harari was born in 1945 in Tel Aviv, Israel. [3] His parents were Polish Jews who at 1933 had immigrated to Palestine before Israel's formation. [3]He was born and raised in Israel. [4]
SanDisk again announced pre-loaded cards in 2008, under the slotMusic name, this time not using any of the DRM capabilities of the SD card. [145] In 2011, SanDisk offered various collections of 1000 songs on a single slotMusic card for about $40, [ 146 ] now restricted to compatible devices and without the ability to copy the files.
EEPROM and flash memory media have individually erasable segments, each of which can be put through a limited number of erase cycles before becoming unreliable. This is usually around 3,000/5,000 cycles [ 5 ] [ 6 ] but many flash devices have one block with a specially extended life of 100,000+ cycles that can be used by the Flash memory ...
Other early cards such as the Bee Card contained non-modifiable ROM, Write once read many EPROM or rewriteable EEPROM memory. [19] In 1992, SanDisk introduced ...
The SD Association was founded January 28, 2000 by SanDisk, Panasonic (Matsushita) and Toshiba – named also as "SD Group". The founding individual members include: Eli Harari, CEO and founder of SanDisk Corporation; Youichi Morishita, President of Panasonic (Matsushita Electric Industrial Co., Ltd)
