Use of FBDIMM Channel as memory channel and coherence channel

摘要

In one embodiment, a node comprises at least one memory control unit configured to couple to an industry standard memory interface for coupling to a memory; and at least one coherence unit configured to transmit and receive coherence messages to and from other nodes to maintain coherent memory among the nodes. The coherence messages are conveyed on a second interface to which the coherence unit is coupled, wherein the second interface includes at least a physical layer as specified by the industry standard memory interface.
