Flash Memory is a non volatile electrically erase- and programmable type of semiconductor memory.
eMMC (embedded Multimedia Card) is a "managed Flash" - Media i.e. Flash-Controller and raw Flash Memory are combined in one common BGA Package. The raw flash management is handled by the Flash controller thus the eMMC user must not take care about bad block management, ecc, wear leveling etc.
MLC means Multi Level Cell. In a MLC two data Bits are keept in one Flash cell. Two Data bits require 4 voltage levels to be maintained in one cell which are detected by comparators. Advantage is a higher Bit density but on the expense of smaller voltage margins in comparison to Single Level Cells (SLC) where one needs to detect only two voltage levels - chareged / non-charge.
The pSLC configuration on muliti level cell ( MLC, TLC) NAND only takes 2 bits for data storage from original 4bit MLC or 8 bits TLC NAND. It can dramatically increase the reliability, endurance of NAND Flash. It makes the SSDs meet high P/E cycle, high TBW demand in industrial and embedded applications and also increases data access performance.
