Abstract
An anti-fuse sensing device and an operation method thereof are provided. The anti-fuse sensing device includes an anti-fuse sensing circuit, a voltage generating circuit, and a power-on detection circuit. During a power-on transient period of the voltage generating circuit, the power-on detection circuit provides an initialization voltage to a control terminal of the anti-fuse sensing circuit to prevent a voltage level of the control terminal of the anti-fuse sensing circuit from being in an unknown state. After the power-on transient period ends, the voltage generating circuit provides a control voltage to the control terminal of the anti-fuse sensing circuit. The anti-fuse sensing circuit senses a resistance state of an anti-fuse based on the control voltage. During the period when the voltage generating circuit provides the control voltage, the power-on detection circuit stops providing the initialization voltage to the control terminal of the anti-fuse sensing circuit.
