DVM16D1L8/4G is an Unbuffered DDR3 512Mx72 small -outline memory module with ECC bits which conforms to JEDEC's PC3L-12800 standard. The assembly is Single-Rank comprised of nine 512Mbx8 DDR3L SDRAMs.One EEPROM with a thermal sensor is used for Serial Presence Detect.Both output driver strength and input termination impedance are programmable to maintain signal integrity on the I/O signals in a Fly-by topology.
