Abstract
The present invention includes: a series circuit which has a negative differential resistance element and another negative differential resistance element that has a control terminal capable of controlling a value of an element current; a transfer gate; a latch circuit which has negative differential resistance elements connected in series; and an inverter circuit which has an FET as a drive element and a negative differential resistance element as a load element. With this, such a flip-flop can be obtained that when a clock signal is applied to a power supply terminal of the series circuit and a control terminal of the transfer gate and an input signal is supplied to the control terminal of the negative differential resistance element, an output is placed at a terminal.
