Abstract
A logic circuit includes two two-terminal switching devices and receives first and second pulses as inputs. Each of the two devices has two different stable resistivity values for each applied voltage that is greater than a first threshold voltage (Vth) and is smaller than a second threshold voltage (Vth) that is larger than Vth. Each switching device, when a voltage less than or equal to Vthis applied, becomes in a first state having the higher resistivity of the two resistivity values, whereas when a voltage more than or equal to Vthis applied, becomes in a second state having the lower resistivity of the two resistivity values. The two devices are connected in series in a direction with uniform polarity to each other. The first and second states are selectively generated in the first and second devices by a combination of inputs of the first and second pulses.
