HMD1M32M2EG Datasheet | Hanbit Electronics

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 puters and an image memory systems, and to the others, which are, requested pact size. The HMD1M32M2G provides mon data and outputs. ..
