Anti-fuse circuit and anti-fuse unit programming state real-time verification
Abstract:
The disclosed anti-fuse circuit includes: an anti-fuse unit; a programming circuit, configured to program the anti-fuse unit according to a programming signal; a verification unit, including a first input terminal, a second input terminal and a first output terminal, the programming signal of the anti-fuse unit is the input signal of the first input terminal, and the data signal stored in the anti-fuse unit is the input signal of the second input terminal. The verification unit verifies the programming state of the anti-fuse unit according to the input signals of the first input terminal and the second input terminal, and the first output terminal outputs a verification signal. The anti-fuse circuit does not need to read out the data signal of the anti-fuse unit to a test machine followed by verifying the programming state of the anti-fuse unit. This anti-fuse circuit saves time and enables high verification accuracy.
