Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR and NAND logic gates. Both use the same cell design, consisting of floating-gate MOSFETs. They differ at the circuit level depending on ...
USB flash drive: Various USB 1.1/2.0/3.0/3.1 2000/2001 1 TB+ (not to scale) Universally compatible across most non-mobile computer platforms, their greater size suits them better to file transfer/storage instead of use in portable devices
Toshiba commercially launched NAND flash memory in 1987. [ 11 ] [ 12 ] Toshiba gave Masuoka a few hundred dollar bonus for the invention, and later tried to demote him. [ 13 ] But it was the American company Intel which made billions of dollars in sales on related technology. [ 13 ]
A flash drive (also thumb drive, memory stick, and pen drive/pendrive) [1] [note 1] is a data storage device that includes flash memory with an integrated USB interface. A typical USB drive is removable, rewritable, and smaller than an optical disc , and usually weighs less than 30 g (1 oz).
Multi-level cell (MLC) flash memory was introduced by NEC, which demonstrated quad-level cells in a 64 Mb flash chip storing 2-bit per cell in 1996. [ 25 ] 3D V-NAND , where flash memory cells are stacked vertically using 3D charge trap flash (CTP) technology, was first announced by Toshiba in 2007, [ 34 ] and first commercially manufactured by ...
Universal Flash Storage (UFS) is a flash storage specification for digital cameras, mobile phones and consumer electronic devices. [ 1 ] [ 2 ] It was designed to bring higher data transfer speed and increased reliability to flash memory storage, while reducing market confusion and removing the need for different adapters for different types of ...
Almost all mobile phones and tablets used this form of flash for main storage until 2016, when Universal Flash Storage (UFS) started to take control of the market. However, as of 2023, eMMC is still used in many consumer applications, including lower-end smartphones, such that Kioxia has introduced new 64 GB and 128 GB eMMC 5.1 modules based on ...
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. These USB flash drives became available from IBM on December 15, 2000, and had a storage capacity of 8 MB, more than five times the capacity of the then-common floppy disks. [5]
