Claim Text:
1. A semiconductor device comprising: a variable resistance first switch which includes a first terminal and a second terminal and whose resistive state changes when a predetermined condition is satisfied after electric power is applied, a variable resistance second switch which includes a third terminal and a fourth terminal and configures an intermediate node by connecting the third terminal and the second terminal, and whose resistive state changes when a predetermined condition is satisfied after electric power is applied, a first wiring which is connected to the first terminal, a second wiring which is connected to the fourth terminal and extends in a direction intersecting with the first wiring in a planar view, a first selection switch element which is connected to the first wiring, and a second selection switch element which is connected to the second wiring, wherein a current or a voltage at the intermediate node is controlled, wherein an intermediate node selection circuit which changes a state of connection between an intermediate node control signal line that transmits a signal for controlling the voltage or the current of the intermediate node and the intermediate node is further provided for the intermediate node, and wherein the intermediate node selection circuit changes the state of the connection between the intermediate node control signal line and the intermediate node based on a signal from a first decode signal line connected to the first selection switch element and a signal from a second decode signal line connected to the second selection switch element.
