A circuit including a data storage element; first and second input circuitry coupled respectively to first and second inputs of the data storage element and each including a plurality of components adapted to generate, as a function of an initial signal, first and second input signals respectively provided to the first and second inputs; wherein the data storage element includes a first storage node and is configured such that a voltage state stored at the first storage node is protected from a change in only one of the 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 the first input signal and by the conduction state of a second transistor coupled to the first storage node and controlled based on the second input signal.
