To program one cell, a voltage charge is sent to the control gate. Both gates will help control the flow of data. NAND memory cells are made with two types of gates, control and floating gates. The FGTs are structured similar to NAND logic gates. The metal-oxide semiconductor typically used is a floating-gate transistor ( FGT). When power is detached from NAND flash memory, a metal-oxide semiconductor will provide an extra charge to the memory cell, keeping the data. NAND flash saves data as blocks and relies on electric circuits to store data. MP3 players, digital cameras and USB flash drives use NAND technology. NAND flash has found a market in devices to which large files are frequently uploaded and replaced. 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. ![]() ![]() NAND flash memory is a type of non-volatile storage technology that does not require power to retain data.
