HMD4M36M3EG
16Mbyte(4Mx36) 72-pin SIMM EDO with Parity MODE, 4K Ref. 5V
Part No. HMD4M36M3E, HMD4M36M3EG
GENERAL DESCRIPTION
The HMD4M36M3E is a 4M x 36 bit dynamic RAM high-density memory module. The module consists of two CMOS 4M
x 16 bit DRAMs in 50-pin TSOP packages and one CMOS 4M 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.
