  • Electric device protection circuit and method for protecting an electric device
    Patent number: 7751163
    Abstract: An electric device protection circuit comprises at least one conductive bridging unit which electrically connects a terminal of the electric device to a protection node set to a protection potential, the protection potential being chosen such that the conductive bridging unit switches from a resistive state to a conductive state in case that the voltage or current at the terminal exceeds a predetermined threshold value.

  • Tunable resistor and method for operating a tunable resistor
    Patent number: 7583527
    Abstract: A tunable resistor includes a resistor input terminal, a resistor output terminal, and at least one current path connected between the resistor input terminal and the resistor output terminal. The at least one current path runs through at least one memory cell of an arrangement of programmable microelectronic memory cells. A resistance adjuster adjusts the current path resistances of the current paths by programming the memory states of corresponding memory cells or which activates/deactivates current paths such that the overall resistance between the resistor input terminal and the resistor output terminal is set to a predetermined resistance target value.
