ABSTRACT:
A logic circuit includes a differential amplifier circuit to which a first input signal and a second input signal both of which are complementary are to be supplied, having a circuit for outputting a first output signal and a second output signal both of which are complementary, the first and second output signals depending on a difference between the first and second input signals, an output terminal, and a switching circuit for, based on a first switching signal and a second switching signal which are complementary, performing a switching operation so that either the first output signal or the second output signal is selected as a signal supplied to the output terminal, wherein the signal supplied to the output terminal is a result of an logical operation of the first input signal and the first switching signal. A current sense amplifier may be substituted for the differential amplifier.
