ABSTRACT:
A detection circuit for detecting unblown and blown conditions for an anti-fuse. The detection circuit includes a precharge circuit for applying a precharge to the anti-fuse during a precharge time interval, and a sampling circuit for coupling the anti-fuse to the detection node to provide a voltage at the detection node that is indicative of the ability of the anti-fuse to retain a charge during the discharge time interval. An output circuit that is coupled to the detection node is responsive to the voltage provided at the detection node to provide a first output for indicating an unblown condition for the anti-fuse and a second output for indicating a blown condition for the anti-fuse.
