An anti-fuse circuit and an integrated circuit (IC) including the same are disclosed, which are applied to a technology for use in all kinds of semiconductor devices or system ICs, each of which includes an anti-fuse circuit using the breakdown phenomenon of a gate oxide, so as to prevent the occurrence of an anti-breakdown phenomenon. The anti-fuse circuit includes an anti-fuse, a breakdown of which occurs by a program voltage, configured to be electrically short-circuited, a read controller configured to be controlled by a read voltage received through the anti-fuse so as to output a short-circuiting status of the anti-fuse, and a switching unit configured to form a path that prevents a current flowing through the anti-fuse from being applied to the read controller during a program operation and prevents a current from flowing in the anti-fuse during a read operation.
