Overview
The JM667QSU-1G is a 128M x 64bits DDR2-667 SO-DIMM. The JM667QSU-1G consists of 8pcs 128M x 8 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.
