The TS256MLQ64V8VL is a 256M x 64bits DDR2-800 

Unbuffered DIMM. The TS256MLQ64V8VL consists of 

16pcs 128Mx8bits DDR2 SDRAMs in 68 ball FBGA 

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

printed circuit board. The TS256MLQ64V8VL 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.
