Detailed explanation-1: -MP3 players, digital cameras and USB flash drives use NAND technology. NAND flash saves data as blocks and relies on electric circuits to store data. When power is detached from NAND flash memory, a metal-oxide semiconductor will provide an extra charge to the memory cell, keeping the data.
Detailed explanation-2: -Originally, BIOS firmware was stored in a ROM chip on the PC motherboard. In later computer systems, the BIOS contents are stored on flash memory so it can be rewritten without removing the chip from the motherboard.
Detailed explanation-3: -Flash memory is used in enterprise data center server, storage and networking technology, as well as in a wide range of consumer devices, including USB flash drives–also known as memory sticks–SD cards, mobile phones, digital cameras, tablet computers and PC cards in notebook computers and embedded controllers.
Detailed explanation-4: -A form of electronically erasable programmable readonly memory (EEPROM), NAND flash is programmed, erased, and reprogrammed in large blocks. It’s called NAND because at the circuit level, it’s similar to the NAND logic function.
