Abstract
Method and apparatus to scrub memory is disclosed. A patrol request, for example a read/write request, may be raised to the memory command scheduler in an out of order memory controller to scrub the memory. The patrol read/write request may be raised as and when patrol interval timer expires. The patrol read/write request may also be raised based on presence of a transaction in-flight to the memory, retry response from the memory command scheduler and correctable or non-correctable error response from the memory command scheduler. An interrupt may be raised to a processor upon completion response from the memory command scheduler.
