Abstract
According to one embodiment, a semiconductor device includes a first circuit, a first terminal, a second terminal, a conductor and a first switch element serially coupled between the first terminal and the second terminal, wherein the first circuit is configured to turn the first switch element to an OFF state when a first condition is satisfied, and the conductor is configured to physically break when a second condition is satisfied.
