HMD8M36M24EG
32Mbyte(8Mx36) 72-pin EDO with Parity MODE 2K Ref. SIMM Design 5V
Part No. HMD8M36M24EG
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 powe red from a single 5V DC power supply and all inputs and outputs are TTL -compatible.
