An integrated circuit has a programmable element with an electrical interconnect resistance that can be varied by programming. An evaluation circuit for the evaluation of the electrical interconnect resistance is connected to the programmable element. The electrical interconnect resistance of the programmable element is read out and evaluated by the evaluation circuit. With a trimming circuit, connected to the evaluation circuit, an operating point of the evaluation circuit is adjusted in dependence on the electrical interconnect resistance that has been read out by the evaluation circuit. In this way, a state of the programmable element can be read out and evaluated largely independently of technological fluctuations.
