144PIN PC133 Unbuffered SO-DIMM
256MB With 16M X 8 CL3
Description
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.
