Device, system and method of multistate cache coherence scheme

摘要

Some embodiments of the invention provide devices, systems and methods of cache coherence. For example, an apparatus in accordance with an embodiment of the invention includes a memory to store a memory line; and a cache controller logic to assign a first cache coherence state to the memory line in relation to a first component, and to assign a second, different, cache coherence state to the memory line in relation to a second, different, component.
