DESCRIPTION

The MH28D72KLG is 134217728 - word x 72-bit Double Data Rate(DDR) Synchronous DRAM mounted module.

This consists of 36 industry standard 64M x 4 DDR Synchronous DRAMs in TSOP with SSTL_2 interface which achieves very high speed data rate up to 133MHz.

This socket-type memory module is suitable for main memory in computer systems and easy to interchange or add modules.

FEATURES
