200PIN DDR2 800 SO-DIMM

2048MB With 128Mx8 CL6

Transcend Information Inc.

Description

The JM800QSU-2G is a 256M x 64bits DDR2-800

SO-DIMM. The JM800QSU-2G consists of 16pcs

128Mx8bits DDR2 SDRAMs in FBGA packages and a

2048 bits serial EEPROM on a 200-pin printed circuit

board. The JM800QSU-2G is a Dual In-Line Memory

Module and is intended for mounting into 200-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.
