Method, apparatus, and system for memory read transaction biasing in mirrored mode to provide thermal management

Abstract

A thermal management that redirects the target of read transactions from a thermally failed Dual Inline Memory Module (DIMM) in one mirror, to the corresponding DIMM in the other mirror. The memory controller or MCH would effectively bias the read transactions toward the mirror that is best able to respond based on thermal feedback. Likewise, this may be used as a temporary redirection that continues for only as long as was required to reduce the operating temperature in the failing DIMM.
