A flip-flop device for storing and outputting a data value includes a controllable memory element configured to be open as a function of a control pulse, a feedback means for comparing a data value present at the memory element and the data value output by the memory element, and for outputting a comparison signal, and a control pulse generator for generating the control pulse as a function of the comparison signal, so that the control pulse generator is put in an activated state when the comparison signal is high, so as to then, in the activated state, open the memory element in response to a clock event. The memory element will then be closed again when the comparison signal indicates that the same values are present at the output and at the input of the memory element.
