Transcend JetRam High-Performance 2GB DDR2-800 240-Pin Module

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.
