Abstract
An RS flip-flop has an inverter, connected to an input terminal of the RS flip-flop, a NOR gate having an Enable-Set input, a NAND gate having an Enable-Reset input, and a first and a second transistor connected to the inverter. The outputs of the NOR and NAND gates are connected, via the gate paths of the first and second transistors, to the gate electrode of a third and a fourth transistor, respectively. The third and the fourth transistor are connected in series and form a holding element, whose common connection point is connected to the output of the inverter and to the output terminal of the flip-flop.
