FAST PAGE MODE 4194304-BIT (262144-WORD BY 16-BIT) DYNAMIC RAM  
DESCRIPTION  
PIN CONFIGURATION (TOP VIEW)  
This is a family of 262144-word by 16-bit dynamic RAMs,  
fabricated with the high performance CMOS process, and is ideal  
for 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 small enough for  
battery back-up application.
