GENERAL DESCRIPTION

The HMD8M36M24EG is a 8M x 36bit dynamic RAM high density memory module. The module consists of twenty four

CMOS 4M x 4bit DRAM 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.
