嵌入式多媒体卡KLMAG1JETD-B041 eMMC 的描述：
SAMSUNG eMMC is an embedded MMC solution designed in a BGA package form. eMMC operation is identical to a MMC device and therefore is a simple read and write to memory using MMC protocol v5.1 which is a industry standard.
eMMC 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 eMMC supports HS400 in order to improve sequential bandwidth, especially
sequential read performance.
There are several advantages of using eMMC. 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 eMMC manages Wear Leveling, Bad Block Management and ECC. The
FTL supports all features of the Samsung NAND flash and achieves optimal performance.
