Internally-generated data storage in spare memory locations

A memory system comprising:

• a memory controller;
• a plurality of memory devices operably coupled to the memory controller;
• and
• a first memory device operably coupled to the memory controller, the first memory device configured to:
• generate, within the first memory device, a plurality of event-based information associated with activity in the memory system;
• store the event-based information in a reserved portion of the first memory device;
• and
• provide the event-based information to the memory controller corresponding with an access of a memory row across the plurality of memory devices associated with the event-based information.

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by processing circuitry to cause the processing circuitry to perform:

• generating, within a first memory device of a memory system, a plurality of event-based information associated with activity in the memory system;
• storing the event-based information in a reserved portion of the first memory device;
• and
• providing the event-based information 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.
