M88DDR4DB02  -  Gen2 DDR4 Data Buffer (DB)

M88DDR4DB02 is a dual 4-bit bidirectional Data Buffer (DB) with differential strobes. The chip is fully compliant with JEDEC DDR4DB02 specification. Nine DBs can be used in conjunction with one DDR4 Registering Clock Driver (RCD) on an LRDIMM to provide advanced memory solutions with higher capacity, higher speed and lower power for next generation server platforms.
