16Mbyte(4Mx36) 72-pin SIMM, EDO with Parity Mode, 2K/4K Ref. 5V
Part No. HMD4M36M9EG , HMD4M36M9EAG
GENERAL DESCRIPTION
The HMD4M36M9EG is a 4M x 36 bit dynamic RAM high-density memory module. The module HMD4M36M8E consists
of eight CMOS 4M x 4 bit DRAMs in 24-pin SOJ packages and one CMOS 4M x 4 bit Quad /CAS DRAM in 28-pin SOJ
package mounted on a 72-pin, double-sided, FR-4-printed circuit board.
A 0.1uF or 0.22uF decoupling capacitor is mounted on the printed circuit board for each DRAM. 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.
