Abstract
A chip includes a logic circuit which has a plurality of transistors and is configured to carry out a logical data processing function, the transistors being operated in a first direction when carrying out the data processing function, and a readout circuit which is configured to control the logic circuit in such a manner that the transistors are operated in a second direction opposite the first direction and is configured to determine an identification of the logic circuit on the basis of an output from the logic circuit when operating the transistors in the second direction.
