SEMICONDUCTOR DEVICE

A semiconductor device includes a storage element write unit including a storage element configured to be electrically written only once and store two values, a write controller connected to the storage element through a first node signal and configured to perform a write to the storage element based on a write control signal instructing a write to the storage element, and a write state detection circuit configured to detect that the storage element is in a write state based on a measurement signal obtained by measuring the first node signal. In a case where the write controller receives a detection signal indicating that the storage element is in the write state from the write state detection circuit after start of a write to the storage element, the write controller stops write operation after a lapse of a predetermined time from detection of the write state of the storage element.
