4Mbyte(1Mx36) 72-pin SIMM EDO with Parity MODE, 1K Ref. 5V
Part No. HMD1M36M3EG
GENERAL DESCRIPTION
The HMD1M36M3EG is a 1M x 36 bit dynamic RAM high-density memory module. The module consists of two CMOS
1M x 16 bit DRAMs in 42-pin TSOP packages and one CMOS 1M x 4bit Quad CAS DRAM in 28pin SOJ package
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.
