240PIN DDR2 400 Registered DIMM
1024MB With 128Mx4 CL3
Transcend Information Inc.

Description
The TS128MQR72V4K is a 128M x 72bits DDR2-400
Registered DIMM. The TS128MQR72V4K consists of 18
pcs 128Mx4 bits DDR2 SDRAMs in 60 ball FBGA
package, 2 pcs register in 96 ball uBGA package, 1 pcs
PLL driver IC and a 2048 bits serial EEPROM on a
240-pin printed circuit board. The TS128MQR72V4K 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.
