Abstract:
1. An anti-fuse repair control circuit comprising: an anti-fuse repair enabling part configured to generate and provide an anti-fuse repair enabling signal corresponding to a repair of an anti-fuse during the repair of the anti-fuse; a power voltage control part configured to prevent transmission of a power voltage to a first circuit part during the repair of the anti-fuse in response to an enablement state of the anti-fuse repair enabling signal; and a back-bias voltage control part configured to prevent transmission of a back-bias voltage to a second circuit part during the repair of the anti-fuse in response to the enablement state of the anti-fuse repair enabling signal, wherein the back-bias voltage control part comprises: a back-bias voltage pumping part for pumping the back-bias voltage; a back-bias voltage output control part providing an output control signal depending on the enablement state of the anti-fuse repair enabling signal; and a back-bias voltage output part selectively outputting the voltage provided from the back-bias voltage pumping part in response to the output control signal provided from the back-bias voltage output control part.
