The JM800QLU-2G is a 256M x 64bits DDR2-800 Unbuffered DIMM. The JM800QLU-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 JM800QLU-2G is a Dual In-Line Memory 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 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.
