Abstract: The invention relates to an integrated digital circuit comprising a logic circuit portion which takes one of at least two different logic states in accordance with provided control signals. In order to minimize the power consumption and to enable a fast start up of the circuit resuming the previous states, it is proposed that it further comprises a non-volatile storage component. The non-volatile storage component takes one of at least two different logic states based on a non-destructive programming, and keeps a programmed logic state for a basically unlimited time and independently of a power supply until a new programming occurs, and is programmed by each change of the logic state of the logic circuit portion. The invention relates equally to a device comprising such a digital circuit and to a method of operating such a digital circuit.
