Transcend JM800QSU-1G Memory Module Computer Component

The JM800QSU-1G is a 128M x 64bits DDR2-800 SO-DIMM. The JM800QSU-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 JM800QSU-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.
