Abstract
Provided is a semiconductor integrated circuit including: an anti-fuse element that electrically connects a first node and a first power supply terminal when data is written and electrically disconnect the first node and the first power supply terminal when data is not written; a first switch circuit that is connected between the first node and a first data line applied with a predetermine first voltage, and enters an off state from an on state according to a first control signal; and a detection part that detects write data of the anti-fuse element according to whether a voltage of the first node is substantially the same as the first voltage or substantially the same as a supply voltage of the first power supply terminal when the first switch circuit enters the off state.
