Abstract:
1. A logic circuit, comprising: a two-terminal bistable switching element that has characteristics such that a state having a first resistance value is entered when a voltage equal to or less than a first threshold voltage is applied, and a state having a second resistance value different from the first resistance value is entered when a voltage equal to or greater than a second threshold voltage which is greater than the first threshold voltage, is applied, and that has characteristics which maintain each of the states when no voltage is applied; a first switching element, one end of which is connected to one of the terminals of the two-terminal bistable switching element; a second switching element, one end of which is connected, via a resistor element, to the other terminal of the two-terminal bistable switching element; and first and second pulse input terminals, respectively connected to the one terminal and the other terminal of the two-terminal bistable switching element; wherein when a bias voltage is applied across the other end of the first switching element and the other end of the second switching element, and a trigger pulse is input from the first and second pulse input terminals.
