A method and apparatus for supporting temporal data and non-temporal data memory accesses in a cache is disclosed. In one embodiment, a specially selected way in a set is generally used for non-temporal data memory accesses. A non-temporal flag may be associated with this selected way. In one embodiment, cache lines from memory accesses including a non-temporal hint may be generally placed into the selected way, and the non-temporal flag then set. When a temporal data cache line is to be loaded into a set, it may overrule the normal replacement method when the non-temporal flag is set, and be loaded into that selected way.
