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.

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.
