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.
An integrated digital circuit comprising:
A device including an integrated digital circuit, which integrated digital circuit comprises:
A method of operating a digital circuit, which digital circuit includes a logic circuit portion which takes one of at least two different logic states in accordance with provided control signals and a non-volatile storage component, which non-volatile storage component takes one of at least two different logic states based on a non-destructive programming and which non-volatile storage component keeps a programmed logic state for a basically unlimited time and independently of a power supply until a new programming occurs, said method comprising operating said logic circuit portion by supplying power and control signals to said logic circuit and programming the respective logic status of said logic circuit portion upon each change of status into said non-volatile storage component.
