摘要：
In one embodiment, the present invention includes a method for receiving a cache access request for data present in a lower-level cache line of a lower-level cache, and sending recency information regarding the lower-level cache line to a higher-level cache. The higher-level cache may be inclusive with the lower-level cache and may update age data associated with the cache line, thus reducing the likelihood of eviction of the cache line. Other embodiments are described and claimed.
