HMD4M64D16V
32Mbyte(4Mx64) Fast Page Mode 4K Ref. 3.3V, DIMM 168 pin
Part No. HMD4M64D16V
GENERAL DESCRIPTION
The HMD4M64D16V is a 4Mx64bits Dynamic RAM high density memory module. The HMD4M64D16V consists of
sixteen CMOS 4Mx4bits DRAMs in SOJ/TSOP 400mil packages mounted on a 168-pin glass-epoxy substrate. A 0.1 or
0.22uF decoupling capacitor is mounted on the printed circuit board for each DRAM. The HMD4M64D16EV is a Dual In-
line Memory Module and is intended for mounting into 168 pin edge connector sockets
