The term eMMC is short for "Embedded Multi-Media Controller" and refers to a package consisting of both flash memory and a flash memory controller integrated on the same silicon die. The eMMC solution consists of at least three components - the MMC (multimedia card) interface, the flash memory, and the flash memory controller - and is offered in an industry-standard BGA package.

Samsung combined those two roles and built the eMCP memory, short for Embedded Multi-chip Package.
The 4GB NAND part is based on the 20nm manufacturing process technology,
while the 256MB, 512MB or 768MB of LPDDR2 DRAM is designed on the 30nm technology
