Transcend 256MB SDRAM 144Pin SO-DIMM PC133 Unbuffer Non-ECC Memory TS32MSS64V6L User Manual

 

 

 

The TS32MSS64V6L is a 32M bit x 64 Synchronous 

Dynamic RAM high-density memory modules. The 
TS32MSS64V6L consists of 16 pieces of CMOS 16Mx8bits 
Synchronous DRAMs in WBGA packages and a 2048 bits 
serial EEPROM on a 144-pin printed circuit board. The 
TS32MSS64V6L is a Dual In-Line Memory Module and is 
intended for mounting into 144-pin edge connector sockets. 

Synchronous design allows precise cycle control with the 

use of system clock. I/O transactions are possible on every 

clock cycle. Range of operation frequencies, programmable 

latencies allow the same device to be useful for a variety of 

high bandwidth, high performance memory system 

applications.
