Radiation hardened circuit

摘要

The invention concerns a circuit comprising: a data storage element (102); first and second input circuitry (104, 104') coupled respectively to first and second inputs (IN1, IN2) of the data storage element and each comprising a plurality of components adapted to generate, as a function of an initial signal (IN), first and second input signals respectively provided to said first and second inputs; wherein the data storage element comprises a first storage node and is configured such that a voltage state stored at said first storage node is protected from a change in only one of said first and second input signals by being determined by the conduction state of a first transistor coupled to the first storage node and controlled based on said first input signal and by the conduction state of a second transistor coupled to the first storage node and controlled based on said second input signal.
