A system comprises processing logic that issues a request associated with an address. The system comprises a first cache that comprises a plurality of line frames. Each line frame has a status bit indicative of how recently that line frame has been accessed. The system comprises a second cache comprising another line frame having another status bit that is indicative of how recently the another line frame has been accessed. The another line frame comprises data other than the another status bit. If one of the plurality of line frames comprises the data associated with the address and the status bit associated with the one of the plurality of line frames is in a predetermined state, the first cache generates a hint transaction signal which is used to update the another status bit. The hint transaction signal does not cause the data to be updated.
