Abstract
A semiconductor device with low power consumption is provided. The semiconductor device includes a first transistor, a second transistor, and a capacitor. The first transistor includes a first gate and a first back gate, and the second transistor includes a second gate and a second back gate. A gate insulating layer for the first back gate has ferroelectricity. The first transistor has a function of, when being in an off state, retaining a first potential corresponding to first data. The second transistor has a function of making an output current flow between a source and a drain of the second transistor.
