In order to reduce power consumption, an arithmetic circuit having a function of performing a logic operation processing based on an input signal, storing a potential set in accordance with the result of the logic operation processing as stored data, and outputting a signal with a value corresponding to the stored data as an output signal. The arithmetic circuit includes an arithmetic portion performing the logic operation processing, a first field-effect transistor controlling whether a first potential, which is the potential corresponding to the result of the logic operation processing is set, and a second field-effect transistor controlling whether the potential of the output signal data is set at a second potential which is a reference potential.
