A storage circuit apparatus includes a support material, a semiconductor chip on which at least one shadow RAM is integrated, a capacitor element and a circuit housing. The storage circuit shadow RAM apparatus is able to perform a STORE operation to secure the RAM content in the non-volatile shadow memory practically independently of the time curve in "power down," without external accessory circuitry. The capacitor element, consisting at least of electrodes and dielectric, is integrated in the circuit housing, and furnishes the energy required for the STORE operation in power-down.
