The JM533QLJ-1G is a 128M x 64bits DDR2-533 

Unbuffered DIMM. The JM533QLJ-1G consists of 16pcs 

64Mx8bits DDR2 SDRAMs in 60 ball FBGA packages 

and a 2048 bits serial EEPROM on a 240-pin printed 

circuit board. The JM533QLJ-1G 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.
