Abstract :
We describe and analyze row/column replacement, the technique currently used to control hard cell defects in semiconductor RAM´s during manufacture. This strategy is shown to be asymptotically ineffective; it is demonstrated that this ineffectiveness may become a limiting issue for very large memory arrays.
