DESCRIPTION

This is family of 4194304 - word by 64 - bit dynamic RAM module. This consists of four industry standard 4Mx16 dynamic RAMs in TSOP and one industry EEPROM 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 of addition of modules
