144PIN PC100 Unbuffered SO-DIMM 
256MB With 16Mx8 CL2
 
 
Description
 
The TS32MSS64V8D2 is a 32M bit x 64 Synchronous 
Dynamic RAM high-density memory modules. The 
TS32MSS64V8D2 consists of 16 pieces of CMOS 
4Mx8bitsx4banks Synchronous DRAMs in TSOP-II 400mil 
packages, a 2048 bits serial EEPROM and a PLL on a 
144-pin printed circuit board. The TS32MSS64V8D2 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.
