1. A memory, comprising:
cache memory to store first data;
backing storage media coupled to the cache memory, the backing storage media to store second data corresponding to the first data in a hierarchical relationship; and
buffer circuitry coupled to the cache memory and the backing store media to cease maintaining the correspondence of the second data to the first data when a status of the first data indicates that the first data no longer corresponds to the second data.
