KLM8G1WEMB-B031 is 64Gb x 1, NAND Flash Memory ( 8GB ).

SAMSUNG e·MMC is an embedded MMC solution designed in a BGA package form. e·MMC operation is identical to a MMC device and therefore is a simple read and write to memory using MMC protocol v5.0 which is a industry standard.

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.

There are several advantages of using e·MMC. It is easy to use as the MMC interface allows easy integration with any microprocessor with MMC host.

Any revision or amendment of NAND is invisible to the host as the embedded MMC controller insulates NAND technology from the host. This leads to faster product development as well as faster times to market.

The embedded flash management software or FTL(Flash Transition Layer) of e·MMC manages Wear Leveling, Bad Block Management and ECC. The FTL supports all features of the Samsung NAND flash and achieves optimal performance.
