JM800QSU-1G | Transcend 1GB DDR2-800 So-Dimm (Notebook)

JM800QSU-1G
200PIN DDR2 800 SO-DIMM
1GB With 128Mx8 CL5
Description 
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.
