Abstract
An anti-fuse circuit includes an anti-fuse coupled to a sensing node, a driving unit configured to rupture the anti-fuse in response to a rupture enable signal, an anti-fuse status detecting unit configured to output an anti-fuse status detecting signal in response to a voltage at the sensing node corresponding to a rupture status of the anti-fuse, and a sensing current supplying unit configured to supply sensing current to the sensing node in response to a rupture sensing signal.
