Abstract
A semiconductor chip includes a plurality of superposed semiconductor levels. The semiconductor levels include a plurality of elementary circuits coupled to a common input node. Sensing circuits are coupled to elementary elements of different levels. The outputs of the sensing circuits are used to generate a number, which serves as an identification number of the semiconductor chip.
