Abstract
A monitor circuit provided in a chip in which a semiconductor integrated circuit is formed. Connection mechanisms and disconnection mechanisms are connected in series in wirings connected to the monitor circuit. Before using the semiconductor integrated circuit, in the state that the connection mechanisms are opened, the monitor circuit is tested without conducting the monitor circuit to the semiconductor integrated circuit. In the case of using the semiconductor integrated circuit, the connection mechanisms are written to close them, so that the monitor circuit is connected to the semiconductor circuit main body and is thus driven. Further, after using the semiconductor integrated circuit, the monitor circuit is separated from the semiconductor integrated circuit by writing the disconnection mechanisms, to be investigated for the characteristic.
