Abstract
A method and apparatus for repairing digital addressable structured arrays, such as memory devices. In one example, a repair mechanism includes adding a number of redundant repair elements to the array, and coupling one or more skip units to the array ahead of the address decode unit(s). The skip unit compares a received logical address with a skip address identifying a defective element within the array, and modifies the input address based on a comparison of the input address and the skip address. The modified address is then decoded to access an element of the array.
