Abstract: A memory chip has a signal line and a complex impedance which is connected to the signal line for termination of the signal line. A memory having such a memory chip and a method for operating a memory chip are also described. The memory chip on the memory having a signal line that is terminated with a complex impedance.

Abstract: A smart card having a support element, at least one electrically conductive contact-making element in a surface area of the support element, and at least one electrical circuit, which is on and/or in the support element and is coupled to the at least one electrically conductive contact-making element. Microstructures and/or nanostructures are incorporated in the at least one electrically conductive contact-making element, of such a size that the microstructures and/or nanostructures absorb electromagnetic radiation at at least one wavelength.

Abstract: The invention relates to a note having a support element with the flexibility of paper, having an electronic chip on and/or in the support element, having a circuit monolithically integrated in the chip and having a field coupling element which is monolithically integrated in the chip, which is set up to interact with an electromagnetic field and which is coupled to the integrated circuit.
