MEMORY ELEMENT AND SIGNAL PROCESSING CIRCUIT

摘要

PURPOSE: A memory device and a signal processing circuit are provided to reduce power consumption by maintaining data after a power voltage supply is stopped. CONSTITUTION: A memory device(100) includes a first circuit and a second circuit. The first circuit includes a first transistor(101a) and a second transistor(102a). The second circuit includes a third transistor(101b) and a fourth transistor(102b). A signal potential corresponding to a first signal is inputted to a gate of the second transistor via the first transistor in an on state. A signal potential corresponding to the second signal is inputted to a gate of the fourth transistor via the third transistor in the on state. The first signal is read using the status of the second transistor and the fourth transistor.
