64Mbyte (16Mx36) EDO/with Parity Mode 4K Ref. 72pin-SIMM Design
Part No. HMD16M36M12EG
GENERAL DESCRIPTION
The HMD16M36M12EG is a 16M x 36bit dynamic RAM high-density memory module. The module consists of eight
CMOS 16M x 4bit DRAMs in 32-pin SOJ or TSOP packages and four CMOS 16Mx1bit DRAMs in SOJ or TSOP packages
mounted on a 72-pin glass-epoxy substrate. 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.
