To reduce power consumption, a memory circuit includes a latch unit in which first data and second data are rewritten and read in accordance with a control signal, a first switch unit that controls rewrite and read of the first data stored in the latch unit by being turned on or off in response to the control signal, and a second switch unit that controls rewrite and read of the second data stored in the latch unit by being turned on or off in response to the control signal. The latch unit includes a first inverter and a second inverter. At least one of the first inverter and the second inverter includes a first field-effect transistor, and a second field-effect transistor that has the same conductivity type as the first field-effect transistor and has a gate potential controlled in accordance with the control signal.
