<p>A redundancy circuit and method are disclosed for replacing at least one defective memory cell in a memory device. The redundancy circuit may include redundant decode circuitry for selectively maintaining an address of a defective memory cell in the memory device, receiving the input address and generating an output signal having a value indicative of whether the input address corresponds to the address of the defective memory cell. The redundancy circuit may further include a plurality of redundant storage circuits for selectively maintaining data values, and redundant control circuitry for selectively and individually accessing a first of the redundant storage circuits based upon the value of the output signal of the redundant decode circuitry. <IMAGE></p> |
