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.
