DESCRIPTION
This is a family of 524288-word by 8-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 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.
