DESCRIPTION
This is a family of 262144-word by 16-bit dynamic RAMs with
Hyper Page mode fuction, fabricated with the high performance
CMOS process, and is ideal for the buffer memory systems of
personal computer graphics and HDD 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.
This device has 2CAS and 1W terminals with a refresh cycle of
512 cycles every 8.2ms.
