GENERAL DESCRIPTION
The HMD4M32M8G is a 4M x 32bit dynamic RAM high-density memory module. The module consists of eight CMOS
4M x 4bit DRAMs in 24-pin SOJ packages mounted on a 72-pin, double-sided, FR-4-printed circuit board. 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 and all inputs and outputs are TTL-compatible.
