Flash Memory is a high-capacity, electrically erasable non-volatile memory, mainly divided into NAND Flash and NOR Flash:
NOR Flash: Supports eXecute-in-Place (XIP), features fast read speed and high reliability, but has smaller capacity and higher cost, commonly used for boot code and firmware storage.
NAND Flash: Offers high density, low cost and large capacity, with block-based erasing and writing, serving as the mainstream solution for SSDs, USB drives and mobile phone storage.
Widely applied in consumer electronics, industrial control, automotive electronics and embedded systems.
