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-alterability (both zero to one and one to … 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 … 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 … 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

NOR and NAND flash differ in two important ways:
• The connections of the individual memory cells are different.
• The interface provided for reading and … See more

Multiple chips are often arrayed or die stacked to achieve higher capacities for use in consumer electronic devices such as multimedia … See more
