DESCRIPTION

This is a family of 1048576-word by 4-bit dynamic RAMS, fabricated with the high performance CMOS process,and is ideal for large-capacity memory systems where high speed, low power dissipation , and low costs are essential.

The use of quadruple-layer polysilicon process combined with silicide technology and a single-transistor dynamic storage stacked capacitor cell provide high circuit density at reduced costs.

Multiplexed address inputs permit both a reduction in pins and an increase in system densities.

Self or extended refresh current is low enough for battery back-up application.
