The origins of flash memory can be traced back to the development of the floating-gate MOSFET (FGMOS), also … 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 … See more

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 freshly erased block, any location within that block can be programme… 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-alterability (both zero to one and one to zero) and random access via externally a… See more

NOR and NAND flash differ in two important ways:
• The connections of the individual memory cells are different.
• The interface provided for reading and writing the memory is different; N… 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, which spread writes over the media and … See more
