Abstract
PURPOSE: To attain miniaturization and long-period stabilization of a memory holding unit by connecting a fixed time-constant circuit in parallel to the input terminal part of a volatile memory unit.
CONSTITUTION: In parallel to the input terminal of volatile microprocessor memory 1 on printed substrate 4, capacitor 3 is connected which is formed of basic cells 15 composed of conductive separators 11, paste electrodes 12, polypropylene porous substance 13, gaskets 14, etc., and has not less than two layers and electrostatic capacity of more than 0.1F. Then, adjusting the internal equivalent series resistance of capacitor 3 to more than 0.1 backs up memory 1 for fixed time by the fixed C-R time-constant circuit. Therefore, a memory holding unit of miniature constitution can be obtained which operates stably for a long time.
