DESCRIPTION

This is a family of 524288-word by 8-bit dynamic RAMs, fabricated with the high performance CMOS process, and is ideal for largecapacity memory systems where high speed, low power dissipation, and low costs are essential.

The use of double-layer metalization process 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.
