KLMAG2WEPD-B031 is one of Samsung Electronics’ eMMC (embedded MultiMediaCard) products, mainly used in devices such as smartphones, tablets, and embedded systems. This product is designed to integrate NAND flash memory and a memory controller as built-in memory, allowing users to easily store and manage data.

e·MMC consists of NAND flash and a MMC controller. 3V supply voltage is required for the NAND area (VDDF or VCC) whereas 1.8V or 3V dual supply voltage (VDD or VCCQ) is supported for the MMC controller. SAMSUNG e•MMC supports 200MHz DDR – up to 400MBps with bus widths of 8 bit in order to improve sequential bandwidth, especially sequential read performance.
