240PIN DDR2 667 Unbuffered DIMM

2GB Kit With 64Mx8 CL5

Transcend Information Inc.

Description

The JM2GDDR2-6K consists of 2pcs 1GB DDR2 SDRAM

module. The 1GB module is a 128M x 64bits DDR2-667

Unbuffered DIMM. The 1GB module consists of 16 pcs

64Mx8bits DDR2 SDRAMs in 60 ball FBGA packages

and a 2048 bits serial EEPROM on a 240-pin printed

circuit board. The 1GB module 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.
