Abstract
An integrated circuit of this application includes a circuit board in which a conductive layer of a desired pattern is formed on a metal substrate through an insulating layer, a circuit element mounted on the insulating layer, and first and second connectors for connecting at least the circuit element and an external device. The circuit element is nondetachably mounted on the insulating layer, and has a nonvolatile content which can be rewritten by an external operation. The first connector connects at least the circuit element to a portion to be controlled, and the second connector connects the circuit element and an external processing device via a path different from that of the first connector so as to process a storage content of the circuit element.
