ABSTRACT:
An autonomous error recovery approach is provided for a memory device of a computing system. In response to a request for data, addressed data and associated control information of the memory device are tested for error. If error is detected, the contents of an addressed storage compartment of a second memory device are automatically retrieved and provided responsive to the request. As an example, the memory device may be a cache and the second memory device may be main memory for the computing system.
