GENERAL DESCRIPTION

ISSI eMMC products follow the JEDEC eMMC 5.1 standard. It is ideal for embedded storage solutions for Industrial

application and automotive application, which require high performance across a wide range of operating

temperatures.

eMMC encloses the 2D MLC NAND and eMMC controller inside as one JEDEC standard package, providing a

standard interface to the host. The eMMC controller directly manages NAND flash, including ECC, wear-leveling,

IOPS optimization and read sensing.
