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 … Ver mais Background The origins of flash memory can be traced back to the development of the floating-gate MOSFET (FGMOS), also known as the floating-gate transistor. The original MOSFET (metal–oxide–semiconductor … Ver mais The low-level interface to flash memory chips differs from those of other memory types such as DRAM, ROM, and EEPROM, which support bit-alterability (both zero to one and one to … Ver mais Because of the particular characteristics of flash memory, it is best used with either a controller to perform wear leveling and error correction or specifically designed flash file systems, which spread writes over the media and deal with the long erase times of NOR … Ver mais Flash memory stores information in an array of memory cells made from floating-gate transistors. In single-level cell (SLC) devices, each cell … Ver mais Block erasure One limitation of flash memory is that it can be erased only a block at a time. This generally sets all … Ver mais NOR and NAND flash differ in two important ways: • The connections of the individual memory cells are different. • The interface provided for reading and … Ver mais Multiple chips are often arrayed or die stacked to achieve higher capacities for use in consumer electronic devices such as multimedia … Ver mais WebBecause of the cell structure, NOR flash is inherently more reliable than other solutions.
