Please check with the seller for availability prior to purchase regardless of quantity in stock shown above. DO NOT MAKE PAYMENT UNLESS YOU HAVE CHECKED STOCKThe JM800QLU-1G is a 128M x 64bits DDR2-800 Unbuffered DIMM. The JM800QLU-1G consists of 8 pcs 128Mx8bits DDR2 SDRAMs in FBGA packages and a 2048 bits serial EEPROM on a 240-pin printed circuit board. The JM800QLU-1G 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.
