Abstract
The present invention relates to an anti-fuse repair control circuit which regulates transmission of a power voltage and a back-bias voltage that are converted to repair an anti-fuse to a circuit part. As such, the present invention prevents the influence of a high power voltage or a low back-bias voltage on a circuit part such as a cell, a peripheral circuit, or a core region during an anti-fuse repair. The anti-fuse repair control circuit includes an anti-fuse repair enabling part providing an anti-fuse repair enabling signal corresponding to a repair of an anti-fuse; a power voltage control part controlling transmission of a power voltage to a first circuit part according to an enablement state of the anti-fuse repair enabling signal; and a back-bias voltage control part controlling transmission of a back-bias voltage to a second circuit part according to the enablement state of the anti-fuse repair enabling signal.
