HMD1M32M2GL

4Mbyte(1Mx32) Fast Page Mode, 1K Refresh, 72Pin SIMM, 5V

Design

Part No. HMD1M32M2GL

DESCRIPTION

The HMD1M32M2GL is an 1M x 32 bits Dynamic RAM MODULE which is assembled 2 pieces of 1M x 16bit DRAMs in 42 pin

SOJ package on single sides the printed circuit board with decoupling capacitors. The HMD1M32M2GL is optimized for

application to the systems, which are required high density and large capacity such as main memory of the computers and an

image memory systems, and to the others, which are, requested compact size.

The HMD1M32M2GL provides common data and outputs.
