Abstract
The cell is realized according to a bistable structure which includes a non-volatile memory element. During the normal operation the structure operates as a static RAM cell with the non-volatile element excluded from the circuit. In case of turn-off of the supply line or after suitable control signals, a particular circuit arrangement allows to execute the programming operation of the non-volatile element, that is the information storage, without current absorption. At the turn-on, the automatic reinstatement of the stored information occurs.
