 Using capacitors to supply power to Cmos RAM

The Sharp pocket computer Model 1500 with about 8k of RAM
uses 2*220 microfarad to keep memory alive
during battery change.
It is certainly good for several minutes; based
on my experience; it may be as long as 20 minutes.
The measured current consumption on the Sharp Model 1200
is about 2 microampere when turned off. It has a 2.4k memory
This machine runs on one set of batteries for about
two years.
