200PIN DDR2 667 SO-DIMM
2048MB With 128Mx8 CL5
Transcend Information Inc. 1
Description
The TS256MSQ64V6U is a 256M x 64bits DDR2-667
SO-DIMM. The TS256MSQ64V6U consists of 16pcs
128Mx8bits DDR2 SDRAMs in 60 ball FBGA packages
and a 2048 bits serial EEPROM on a 200-pin printed
circuit board. The TS256MSQ64V6U 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.
