Abstract
An anti-fuse circuit in which anti-fuse program data may be monitored outside of the anti-fuse circuit and a semiconductor device including the anti-fuse circuit are disclosed. The anti-fuse circuit includes an anti-fuse array, a data storage circuit, and a first selecting circuit. The anti-fuse array includes one or more anti-fuse blocks including a first anti-fuse block having a plurality of anti-fuse cells and the anti-fuse array is configured to store anti-fuse program data. The data storage circuit is configured to receive and store the anti-fuse program data from the anti-fuse array through one or more data buses. The first selecting circuit is configured to output anti-fuse program data of a selected anti-fuse block of the one or more anti-fuse blocks in response to a first selection signal.
