In a semiconductor device and a write control circuit, a voltage detection unit detects a write voltage supplied to a storage element (electrical fuse element) in which only single writing is electrically performed and, when the write voltage is equal to or more than a predetermined threshold voltage, allows the write control unit to stop writing to the electrical fuse element regardless of the write signal. The above processing permits the write control circuit to suppress false writing caused by the fact that abnormality occurs in a write voltage and it becomes an overvoltage.
