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 … 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, … 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 stores only one bit of information. 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 Web30 de abr. de 2001 · We present the results of investigations into the causes of threshold voltage instabilities in NOR-type flash memory cells due to charge loss and charge gain. …
