The TX1200QLJ-2GK consists of 2pcs 1GB DDR2 

SDRAM module. The 1GB module is a 128M x 64bits 

DDR2-1200 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.
