Abstract
A circuit for replacing an array element with a redundant element in a semiconductor device is designed with a programmable circuit (128) storing an internal address and coupled to receive a buffered address (120 and 122). The programmable circuit (128) produces first (130) and second (132) redundant addresses in response to the internal and buffered addresses (120 and 122). A first decoder circuit (140), produces a signal to enable the redundant element (142) in response to the first redundant address (130). A second decoder circuit (148) produces a signal to enable the array element (150) in response to the second redundant address (132).
