Abstract:
A semiconductor circuit configuration, comprising:at least one first potential device for making available a first potential; at least one second potential device for making available a second potential; at least one programmable element having a first connecting terminal and a second connecting terminal, said programmable element having an electrical state able to be permanently varied by applying between said first connecting terminal and said second connecting terminal a potential difference having a value reaching a burning voltage predefined for said programmable element; a first electrical connecting device connected between said programmable element and said first potential device, said first electrical connecting device providing a conductive connection between said first connecting terminal of said programmable device and said first potential device; a second electrical connecting device connected between said programmable element and said second potential device, said second electrical connecting device providing a conductive connection between said second connecting terminal of said programmable device and said second potential device; a circuit region; and controllable switching devices, including a first switching device connected between said circuit region and said first connecting terminal and a second switching device connected between said circuit region and said second connecting terminal, said controllable switching devices disconnecting in a controllable manner an electrical state of said programmable element from said circuit region during a burning operation.
