ABSTRACT:
Method and apparatus for detecting and correcting memory storage data errors in a system utilizing parity error detection. An error detected in the memory storage device results in a parity error being reported, thereby causing the corresponding address location to be deactivated. Once deactivated, no further reading or writing is performed at that address location for a predetermined time period. The parity error reporting and address deactivation is accomplished without an access time penalty and requires a reduced number of I/O pins.
