摘要：
A caching circuit includes tag memories for storing tagged addresses of a first cache. On-chip data memories are arranged in the same die as the tag memories, and the on-chip data memories form a first sub-hierarchy of the first cache. Off-chip data memories are arranged in a different die as the tag memories, and the off-chip data memories form a second sub-hierarchy of the first cache. Sources (such as processors) are arranged to use the tag memories to service first cache requests using the first and second sub-hierarchies of the first cache.
