Abstract: Systems and methods for tracking addresses stored in non-home locations in a cache. A method includes determining if an address that is to be stored in a cache is to be stored in a non-home location, determining if a directory has a location available for storing an identifier of the non-home location and if one or more locations of the directory are available for storing an identifier of the non-home location, storing an identifier of the non-home location in one of the one or more locations of the directory. The method further includes invalidating a non-home location in the cache that corresponds to one of the one or more locations of the directory, if none of the one or more locations of the directory are available for storing an identifier of the non-home location, and storing an identifier of the non-home location in the one of the one or more locations.
