200PIN DDR2 667 SO-DIMM
512MB With 32Mx16 CL5
JM667QSM-512M
Description
Placement
The JM667QSM-512M is a 64M x 64bits DDR2-667
SO-DIMM. The JM667QSM-512M consists of 8pcs
32Mx16bits DDR2 SDRAMs in 84 ball FBGA packages
and a 2048 bits serial EEPROM on a 200-pin printed
circuit board. The JM667QSM-512M 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.
