DESCRIPTION

The MH32V725BST is 33554432-word x 72-bit dynamic ram stacked structural module. This consist of thirty-six industry standard 16M x 4 dynamic RAMs in TSOP and two industry standard input buffer in TSSOP.

The mounting of TSOP on a card edge dual in-line package provides any application where high densities and large of quantities memory are required.

This is a socket-type memory module ,suitable for easy interchange or addition of module.
