DESCRIPTION

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.

This device has 2CAS and 1W terminals with a refresh cycle of 512 cycles every 8.2ms.
