An apparatus for and method of improving the efficiency of a level two cache memory. In response to a level one cache miss, a request is made to the level two cache. A signal sent with the request identifies when the requester does not anticipate a near term subsequent use for the requested data element. If a level two cache hit occurs, the requested data element is marked as least recently used in response to the signal. If a level two cache miss occurs, a request is made to level three storage. When the level three storage request is honored, the requested data element is immediately flushed from the level two cache memory in response to the signal.
