摘要
A repair circuitry consisting of at least one electrical fuse forming part of a conduction path between a positive voltage supply (VQ) pad and a complimentary lower voltage supply source (Vss). The repair circuitry includes at least one switching device and at least one control circuit. The at least one first switching device has a control terminal and is coupled between the Vss and the at least one electrical fuse. The at least one control circuit is coupled to the control terminal and the Vss respectively. Upon an application of a positive high voltage to the VQ pad, the at least one control circuit delays the turn-on state of the at least one first switching device for a predetermined period of time, thereby preventing the at least one electrical fuse from being mistakenly programmed.
