Abstract:
A cache memory device includes a plurality of cache areas, each the cache area comprising a plurality of entries. The cache memory device is configured to maintain a separate lock attribute for each the cache area and temporarily assign possession of a lock attribute for a particular the cache area to a processor thread attempting to update the particular the cache area, the processor thread being unable to update the particular the cache area without possession of the lock attribute for the particular the cache area.
