M5M44260CJ,TP-5,-5S : Under development
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.
