Abstract

The flip-flop according to the invention serves for storing an item of logic state information and has at least one data input and at least one data output. The flip-flop comprises at least one latch stage for storing the state information if the flip-flop is switched on. Furthermore, the flip-flop according to the invention comprises at least one memory cell having a capacitance as storage element. In this case, the at least one memory cell serves for storing the state information if the flip-flop is switched off.
