200PIN DDR2 533 SO-DIMM

256MB With 32Mx16 CL4

Transcend Information Inc.

Description Placement

The JM435Q644A-5 is a 32M x 64bits DDR2-533

SO-DIMM. The JM435Q644A-5 consists of 4pcs

32Mx16its DDR2 SDRAMs in 84 ball FBGA packages

and a 2048 bits serial EEPROM on a 200-pin printed

circuit board. The JM435Q644A-5 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.
