摘要： An aspect includes providing communication links from a memory controller to contents of a plurality of bit locations in a plurality of memory devices. A failing bit location in the plurality of bit locations is detected by the memory controller. A replacement bit location for the failing bit location is selected and a replacement communication link to the replacement bit location is provided by the memory controller. A request to access contents of the failing bit location received after the selecting and providing the replacement communication link is performed by accessing contents of the replacement bit location via the replacement communication link.

摘要： An aspect includes generating, within a first memory device of a memory system, a plurality of event-based information associated with activity in the memory system. The event-based information is stored in a reserved portion of the first memory device. The event-based information is provided to a memory controller of the memory system corresponding with an access of a memory row across a plurality of memory devices of the memory system associated with the event-based information.
