NAND Flash

NAND Flash memory is a type of Flash Memory. It belongs to non-volatile memory that can be electrically erased and reprogrammed. Data stored in a NAND Flash can be maintained without external power supply. NAND Flash offers a maximum chip capacity with relatively low cost. Thus it is being widely used in applications with mass data storage like SSD drive, SD cards as well as embedded systems.

How it works

Same as NOR Flash, the NAND Flash memory cell utilizes the charge state of a floating gate to store binary information. Data can be read and written in pages, but they can only be erased at the level of entire blocks consisting of multiple pages.

There are different types of NAND Flash:

SLC: single-level cell: stores one bit per cell.

MLC: multiple-level cell: stores two bits per cell

TLC: triple-level cell: stores three bits per cell.

QLC: quad-level cell: stores four bits per cell.
