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 EDO  
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. The lower supply (3.3V) operation, due to the  
optimization of transistor structure, provides low power dissipation  
while maintaining high speed operation. 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.
