A circuit and method are provided for disabling a defective normal element using a flip-flop. The flip-flop has two states. In a first state, to which the flip-flop can be set on application of power, the flip-flop enables a normal decoder, corresponding to the normal element, to respond to a respective address for the normal element. In a second state, to which the flip-flop can be set only upon coincident selection of a defective normal element and a programmed redundant element during an initialization routine, the flip-flop disables the normal decoder from responding to any address.
