200PIN DDR2 667 SO-DIMM
JM667QSU-1G 1GB With 128Mx8 CL5
Description Placement
The JM667QSU-1G is a 128M x 64bits DDR2-667
SO-DIMM. The JM667QSU-1G consists of 8pcs 128Mx8
bits DDR2 SDRAMs in 60 ball FBGA packages and a
2048 bits serial EEPROM on a 200-pin printed circuit
board. The JM667QSU-1G 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.
