240PIN DDR2 800 ECC Unbuffered DIMM

2GB With 128Mx8 CL6

Transcend Information Inc.

Description Placement

The TS256MLQ72V8U is a 256M x 72bits DDR2-800

Unbuffered DIMM. The TS256MLQ72V8U consists of 18

pcs 128Mx8bits DDR2 SDRAMs in FBGA packages and

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

board. The TS256MLQ72V8U 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.
