DDR3 Low Voltage 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 Low Voltage 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.
