PURPOSE:To provide a semiconductor device having a redundant circuit and a self-diagnositic circuit, in which a defective part to be replaced with the redundant circuit is easily determined. CONSTITUTION:A redundant circuit 2 and a self-diagnostic circuit 3 are provided in a semiconductor device. The self-diagnositic circuit includes a memory 4 and an output circuit 5. When the self-diagnostic circuit detects a defective part, the location of the defective part is stored in the storage means, and the output means produces information on the location of the defective part. |
