HMD1M32M2EG

HANBit HMD1M32M2EG 4Mbyte(1Mx32) EDO Mode, 1K Refresh, 72Pin SIMM, 5V Design Part No. HMD1M32M2EG DESCRIPTION The HMD1M32M2EG 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 HMD1M32M2EG 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 HMD1M32M2G provides common data and outputs.
