240PIN DDR2 533 Registered DIMM

2048MB With 128Mx4 CL4

Transcend Information Inc.

Description

The TS256MQR72V5K is a 256M x 72bits DDR2-533

Registered DIMM. The TS256MQR72V5K consists of 36

pcs 128Mx4 bits DDR2 SDRAMs in 60 ball FBGA

package, 4 pcs register in 96 ball uBGA package, 1

piece PLL driver IC and a 2048 bits serial EEPROM on a

240-pin printed circuit board. The TS256MQR72V5K 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.
