NAND memory is a type of non-volatile flash memory. This means it retains data even when power is turned off. The name NAND comes from the NAND logic gate, which is fundamental to its design. NAND flash memory is characterized by its high density and lower cost per bit compared to NOR flash memory, making it suitable for mass storage applications. It stores data in memory cells arranged in a matrix. Each cell can hold one or more bits of data, depending on the type of NAND flash, such as single-level cell (SLC), multi-level cell (MLC), triple-level cell (TLC), and quad-level cell (QLC). The density and cost advantages of NAND flash are achieved through a serial data interface and a more complex internal architecture compared to NOR flash. Data is read and written in blocks, and erase operations occur on larger sectors, which can lead to slower random access times but efficient sequential operations. NAND flash is widely used in solid-state drives (SSDs), USB flash drives, memory cards (like SD cards), and smartphones. Its endurance, or the number of write/erase cycles a cell can withstand, varies significantly between different types, with SLC offering the highest endurance and QLC the lowest.
