Embodiments of methods and systems for controlling access to information stored on memory or data storage devices are disclosed. The filter network comprises a superconducting filter and a non-superconducting filter, or a combination thereof to form multiplexers. The metal support disk is locked in place within the open end of the anode can with insulating sealing material therebetween. Thus, the present invention provides a filter which may easily be installed by an airline passenger so as to mitigate airborne contaminants from the air supply nozzle of the airliner. In response to detection of a failing storage location in any of the plurality of memory arrays, the shared BIST and repair system applies a common address remapping to all of the plurality of memory arrays to remap, in each memory array, the address associated with the failing storage location to a different storage location.
