Flash memory - Wikipedia

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 … See more 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 … See more The low-level interface to flash memory chips differs from those of other memory types such as DRAM, ROM, and EEPROM, which support bit … See more NOR and NAND flash differ in two important ways: • The connections of the individual memory cells are different. See more Multiple chips are often arrayed or die stacked to achieve higher capacities for use in consumer electronic devices such as multimedia players or GPSs. The capacity scaling (increase) of flash chips used to follow Moore's law because they are manufactured … See more Flash memory stores information in an array of memory cells made from floating-gate transistors. In single-level cell (SLC) devices, each cell stores only one bit of information. Multi-level cell (MLC) devices, including triple-level cell (TLC) devices, can store more than … See more Block erasure One limitation of flash memory is that it can be erased only a block at a time. This generally sets all bits in the block to 1. Starting with a … See more 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, … See more WebJul 23, 2024 · The downside of smaller blocks, however, is an increase in die area and memory cost. Because of its lower cost per bit, NAND Flash can more cost-effectively support smaller erase blocks compared to … WebA flash memory is currently structured in at least four different ways with different features. They are NOR type, NAND type, AND type, and DINOR type. The first two types have been widely used. A NOR-type flash memory is illustrated in Fig. 15.
