Memory repair system and method

A memory system comprising:

• an array of memory cells comprising redundant memory cells, wherein the redundant memory cells comprise at least two of (i) a redundant row of memory cells and (ii) a redundant column of memory cells;
• and
• a repair module 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 having non-operational memory cells with selected rows or columns of the redundant memory cells based on X predetermined sequences of substitutions, where X is an integer greater than 1,
• wherein 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.
