EDO (HYPER 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 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.
