What is the difference between NAND and NOR flash?

NAND flash memory is a type of nonvolatile storage technology that does not require power to retain data. An important goal of NAND flash development has been to reduce the cost per bit and to increase maximum chip capacity so that flash memory can compete with magnetic storage devices, such as hard disks.

What is NAND flash wear-out?

  • NAND flash wear-out is the breakdown of the oxide layer within the floating-gate transistors of NAND flash memory . All of the bits in a NAND flash block must be erased before new data can be written. When the erase process is repeated, it eventually breaks down the oxide layer within the floating-gate transistors of the NAND flash.

How does NAND flash memory work?

  • Flash memory is a kind of Electronically Erasable Programmable Read Only Memory. In a Nand flash memory, the memory cells are connected in series. All the data is recorded in a transistor called Floating Gate. The other transistor named control Gate controls charges flow from the Source to the Drain.

What is the difference between NAND and NOR flash?What is the difference between NAND and NOR flash?

• NOR flash is more reliable and has less percentage of bit flipping, while NAND flashes require an addition bit for error management. • NAND flashes are suitable for data storage while NOR flashes are suitable for code storage. • NAND flash memory is cheaper compared to NOR flash memories in terms of cost per volume.
