DDR3 ECC SO-DIMM is high-speed, low power memory module that use

DDR3 SDRAM in FBGA package and a 2048 bits serial EEPROM on a

204-pin printed circuit board. DDR3 ECC SO-DIMM is a Dual In-Line

Memory Module and is intended for mounting into 204-pin edge

connector sockets.

Synchronous design allows precise cycle control with the use of system

clock. Data I/O transactions are possible on both edges of DQS. Range

of operation frequencies, programmable latencies allow the same device

to be useful for a variety of high bandwidth, high performance memory

system applications.
