Zusammenfassung:A CAM system is disclosed in which requests for address translation are provided as input search data to a dynamic compare bitline generator. The dynamic compare bitline generator also receives a compare mask and applies the compare mask to associated input search data bits on a per bit basis. The mask contains information that specifies a selected page size and a selected logic mode that can be applied to a compare array in which the specified search is conducted. The compare array is coupled to a data array to which the compare array indicates a result of the search.
