240Pin DDR3 1333 UDIMM
1GB Based on 128Mx8
AQD-D31GN13-SX
Description
AQD-D31GN13-SX is a DDR3 Unbuffered, non-ECC
high-speed, low power memory module that use 8 pcs of
128Mx8bits DDR3 SDRAM in FBGA package and a 2048
bits serial EEPROM on a 240-pin printed circuit board.
AQD-D31GN13-SX is a Dual In-Line Memory Module and
is intended for mounting into 240-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.
