Abstract: A dedupable cache is disclosed. The dedupable cache may include cache memory including both a dedupable read cache and a non-dedupable write buffer. The dedupable cache may also include a deduplication engine to manage reads from and writes to the dedupable read cache, and may return a write status signal indicating whether a write to the dedupable read cache was successful or not. The dedupable cache may also include a cache controller, which may include: a cache hit/miss check to determine whether an address in a request may be found in the dedupable read cache; a hit block to manage data accesses when the requested data may be found in the dedupable read cache; a miss block to manage data accesses when the requested data is not found in the dedupable read cache; and a history storage to store information about accesses to the data in the dedupable read cache.
