System and method for improving cache efficiency

摘要

A method and computer program product for receiving a newly-received data portion for storing within a cache memory system. A determination is made concerning whether the newly-received data portion corresponds with at least one data portion previously written to a non-volatile, memory system. If the newly-received data portion does not correspond with at least one previously-written data portion, the newly-received data portion is stored within the cache memory system using a protected data storage methodology.
