Abstract
According to one embodiment, a semiconductor device includes a structure, an insulating film, a control electrode, first and second electrodes. The structure has a first surface, and includes a first, a second, and a third semiconductor region. The structure has a portion including the first, second, and third semiconductor regions arranged in a first direction along the first surface. The insulating film is provided on the first surface. The control electrode is provided on the insulating film. The first electrode is electrically connected to the third semiconductor region. The second electrode is electrically connected to the first semiconductor region. The insulating film includes a charge trap region. A bias voltage is applied to the first and second electrodes, and includes a shift voltage. The shift voltage shifts a reference potential of a voltage applied to the first and second electrodes by a certain voltage.
