DESCRIPTION

The MH8V644AWZJ is 8388608-word x 64-bit dynamic ram module. This consist of eight industry standard 8M x 8 dynamic RAMs in SOJ and one industry standard EEPROM is TSSOP.

The mounting of SOJs and TSSOP 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.
