A0-A10 : Address Input (2K Ref) *Note:A11 is used for only HMD4M36M9EA 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. FEATURES w Part Identification HMD4M36M9E----2048 Cycles/32ms Ref.
