Description
The JM667QLJ-512M is a 64M x 64bits DDR2-667
Unbuffered DIMM. The JM667QLJ-512M consists of 8
pcs 64Mx8bits DDR2 SDRAMs in 60 ball FBGA
packages and a 2048 bits serial EEPROM on a 240-pin
printed circuit board. The JM667QLJ-512M 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.
