Abstract
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.
Claims6
A memory storage circuit comprising:
- a support material, said support material including a lead frame;
- a semiconductor chip on which at least one shadow RAM is integrated;
- and
- a capacitor element arranged to furnish energy required for a STORE operation in said shadow RAM in response to a “power down” condition, said capacitor element having electrodes and dielectric, said semiconductor chip being mechanically and electrically coupled to said lead frame and said capacitor element being mechanically and electrically coupled to at least one of said lead frame and said semiconductor chip.
