SEMICONDUCTOR DEVICE HAVING ELECTRICAL FUSE AND CONTROL METHOD THEREOF |
摘要 |
To provide an electrical fuse that is connected to a detection node via a selective transistor, a precharge transistor that precharges the detection node in a state where the selective transistor is off; a bias transistor that passes a bias current to the detection node in a state where the selective transistor is on and the precharge transistor is off, and a detection circuit that detects a potential of the detection node in a state where the bias current is flowing into the detection node, wherein the bias transistor reduces an amount of the bias current in a stepwise manner or a continuous manner.
