200PIN DDR2 800 SO-DIMM

1GB With 128Mx8 CL5

Transcend Information Inc.

Description

The JM800QSU-1G is a 128M x 64bits DDR2-800

SO-DIMM. The JM800QSU-1G consists of 8pcs 128Mx8

bits DDR2 SDRAMs in 60 ball FBGA packages and a

2048 bits serial EEPROM on a 200-pin printed circuit

board. The JM800QSU-1G 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.
