The SAMSUNG e•MMC is an embedded MMC solution designed in a BGA package form. e•MMC operation is identical to a MMC card and therefore is a simple read and write to memory using MMC protocol v4.41 which is a industry standard.
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.
