A method of conjoint detection of a set of CDMA codes received at a plurality of antennas of a receiver like a mobile telephone receiver. Further a method to operate a processing system comprising multiple processing devices and multiple memory protection units associated to the multiple processing devices. The conductive adhesive film is positioned between the plurality of front electrodes and the interconnector in the second direction crossing the plurality of front electrodes and electrically connects the plurality of front electrodes to the interconnector. This makes it possible, in the case of use in a data processing system, to dispense with a DRAM controller provided outside the memory chip. This cycle is repeated continuously as the paper is being manufactured.
