The JM667QLU-2G is a 256M x 64bits DDR2-667Unbuffered DIMM. The JM667QLU-2G consists of 16pcs 128Mx8bits DDR2 SDRAMs in 68 ball FBGA packages and a 2048 bits serial EEPROM on a 240-pin printed circuit board. The JM667QLU-2G is a Dual In-LineMemory Module and is intended for mounting into 240-pin edge connector sockets.
Synchronous design allows precise cycle control with the use of system clock. Data I/O transactions are possibleon both edges of DQS. Range of operation frequencies,programmable latencies allow the same device to beuseful for a variety of high bandwidth, high performancememory system applications.
