A semiconductor device that retains data even when power is cut off is provided. A first transistor, a second transistor, a third transistor, and a capacitor are included, and one of a source electrode and a drain electrode of the first transistor is a source of the third transistor. One of the electrode and the drain electrode and one electrode of the capacitor are electrically connected, and the gate electrode of the second transistor is electrically connected to the other of the source electrode and the drain electrode of the third transistor. .
