Abstract
Provided is a semiconductor device capable of detecting an abnormal state in which two fuses are both short-circuited or cut. The semiconductor device includes: a trimming circuit having a first fuse and a second fuse connected in series; a current source circuit configured to supply current to the trimming circuit; and a determination circuit configured to determine whether a connection state or disconnect state of the first fuse and the second fuse are abnormal or not based upon signals derived from an output signal of the trimming circuit.
