SEMICONDUCTOR CIRCUIT, METHOD FOR DRIVING THE SAME, STORAGE DEVICE, REGISTER CIRCUIT, DISPLAY DEVICE, AND ELECTRONIC DEVICE

摘要

PURPOSE: A semiconductor circuit, a driving method thereof, a memory device, a register circuit, a display device, and an electronic device are provided to reduce power consumption by suppressing a leakage current. CONSTITUTION: A first capacitive device(103) is electrically connected to a diode. A second capacitive device(105) is electrically connected in parallel to the diode and includes a first electrode and a second electrode. A transistor(111) includes a back gate which is electrically connected to the diode and includes an oxide semiconductor in a channel.
