GENERAL DESCRIPTION
The HMD4M32M2 is a 4M x 32 bit dynamic RAM high-density memory module. The module consists of two CMOS 4M x
16 bit DRAMs in 50-pin TSOP packages mounted on a 72-pin. A 0.1 or 0.22uF decoupling capacitor is mounted on the
printed circuit board for each DRAM components. The module is a single In-line memory module with edge connections
and is intended for mounting in to 72-pin edge connector sockets. All module components may be powered from a single
5V DC power supply. All inputs and outputs are TTL-compatible.
