200PIN DDR2 800 SO-DIMM
1GB With 128Mx8 CL6
Transcend Information Inc.
Description
The TS2QSU23003-4S is a 128M x 64bits DDR2-800
SO-DIMM. The TS2QSU23003-4S consists of 8pcs
128Mx8bits DDR2 SDRAMs in FBGA packages and a
2048 bits serial EEPROM on a 200-pin printed circuit
board. The TS2QSU23003-4S is a Dual In-Line Memory
Module and is intended for mounting into 200-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.
