Abstract
A memory system includes an array of memory cells. The array of memory cells includes redundant memory cells. The redundant memory cells include at least two of a redundant row and a redundant column of memory cells. The repair module is configured to (i) identify at least two of a row and a column of the array of memory cells having non-operational memory cells and (ii) substitute the at least two of the row and the column of the array of memory cells with selected rows or columns of the redundant memory cells based on X predetermined sequences of substitutions. The repair module is configured to detect a failure in the array of memory cells that cannot be repaired using the X predetermined sequences of substitutions, and use an alternative repair sequence to repair the non-operational memory cells based on the detection of the failure.
