NAND flash

NAND flash is a type of non-volatile memory commonly used for storage in devices like USB drives, SSDs, and smartphones. Unlike traditional hard drives, it retains data even when powered off. NAND flash consists of cells that store bits of information in a grid-like structure. Data is written in blocks, which makes it fast and efficient for reading and writing. It is popular due to its compact size, speed, and ability to withstand physical shock, contributing to its use in a range of consumer electronics and industrial applications.
