Abstract
An integrated circuit disclosed in this application includes a circuit board in which a conductive layer having a desired pattern is formed on a metal substrate through an insulating layer, and a circuit element group mounted on the insulating layer and connected to the predetermined conductive layer. A judgment circuit for discriminating on the basis of a potential of the metal substrate which one of at least two different logic processing modes is set is formed on the insulating layer. The circuit element group includes a circuit element including a logic processing unit having at least two different logic processing contents. The circuit element selectively switches and executes a logic processing operation corresponding to the logic processing mode discriminated by the judgment circuit from the at least two different logic processing contents.
