ABSTRACT:
An electronic device, such as an integrated circuit, is provided with elements, all of which are never used in a single application. These elements are not absolutely decoys or dummys, although this is a possibility. For a particular application, the elements are so chosen that, in conjunction with a supplementary logic package, they provide the desired functions. The logic elements used as well as the functions of the main logic package of the device are determined by the supplementary logic. The combined logic is in no way determined by coding or decoding; this logic is specific and both parts together form an electronic component or device. The complete logic is therefore similar to a hybrid circuit but without the wired connections. If this device is compromised to an enemy or a business competitor, the main logic package or packages of the the device need not be newly developed; only the supplementary logic package or packages must be replaced. The function of the device and therefore the function of the equipment using it can thus be changed when the need arises. These additional functions as well as the dummy functions would of course be planned and developed from the beginning.
