MicroP2 is a SDXC/SDHC card conforming to UHS-II (Ultra High Speed bus), and can be read by common SDHC/SDXC card readers. xD: Olympus, Fujifilm, Sony Standard 2002–2007 512 MB Slim and small (20 mm × 25 mm × 1.78 mm), electrically identical to SmartMedia, no wear-leveling controller, up to 512 MB [8] Type M 2005 2 GB
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.
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]
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.
SanDisk Professional (previously G-Technology) is a brand of Western Digital that produces external storage products designed and marketed for the Macintosh, creative pro, photography and A/V markets. [1] Its USB, FireWire, eSATA, SAS, SCSI Thunderbolt, and Fibre Channel systems support all levels of audio/video production. [2]
SanDisk X4 flash memory cards, introduced in 2009, was one of the first products based on NAND memory that stores 4 bits per cell, commonly referred to as quad-level-cell (QLC), using 16 discrete charge levels (states) in each individual transistor. The QLC chips used in these memory cards were manufactured by Toshiba, SanDisk and SK Hynix. [30 ...

The oxide keeps the electrons confined to the floating gate. Degradation or wear (and the limited endurance of floating gate Flash memory) occurs due to the extremely high electric field (10 million volts per centimeter) experienced by the oxide. Such high voltage densities can break atomic bonds over time in the relatively thin oxide ...
