Abstract A method for performing a repair operation in a computer system using arrays having array cells includes detecting an error in an array. In response to detecting the error, error information is written to an error trap register. The error information includes error data and associated error detection information and a position in an array row. The error information is read from the error trap register and a corresponding data copy is determined and fetched in the computer system. One or more exact bit positions that caused the error are determined by comparing the error data with the corresponding data copy. The array cells which are associated with the determined one or more bit positions are disabled.
