Overview
HANBit HMD4M32M8G 16Mbyte(4Mx32) Fast Page Mode, 2K/4K Refresh 72Pin SIMM Part No.
HMD4M32M8G, HMD4M32M8AG GENERAL DESCRIPTION The HMD4M32M8G is a 4M x 32bit dynamic RAM high-density memory module.
The module consists of eight CMOS 4M x 4bit DRAMs in 24-pin SOJ packages mounted on a 72-pin, double-sided, FR-4-printed circuit board.
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.
