Abstract
An embodiment of the present disclosure provides an anti-fuse circuit, including: an anti-fuse unit; a programming circuit connected to the anti-fuse unit, and the programming circuit performs programming of the anti-fuse unit according to the programming control signal and the programming signal; the read unit reads the anti-fuse unit to obtain a data signal; the verification control unit controls the electrical connection between the reading unit and the anti-fuse unit according to the verification enable signal and the programming signal of the anti-fuse unit, when verifying the programming state of the anti-fuse unit. When the anti-fuse circuit verifies the programming state of the anti-fuse unit, it controls the electrical connection between the read unit and the anti-fuse unit according to the verification enable signal and the programming signal of the anti-fuse unit, to realize real-time verification of programming status.
