Abstract: Method and system for limiting the effects of data bit cell errors or error control bit errors that are uncorrectable in a computer. When a corrupted data bit cell is found, the content of the corrupted data bit cell is replaced by an error control bit from an error control bit segment associated with the data bit segment, the error control procedure for this (modified) data bit segment is disabled, and this modified data bit segment is flagged to indicate that the error control procedure for this modified data bit segment is disabled. A corrupted error control bit cell is processed in a similar manner. When a correctable bit error, not stored in a corrupted bit cell, is found, the bit error is corrected by the error control mechanism.
