Abstract
A monolithically integrated circuit in the packed state has at least one characteristic value and/or at least one function which is able to be varied by applying at least one striking potential to at least two of the standard terminal connections leading to the outside of the integrated circuit.
Claims14
An integrated circuit comprising:
- at least one adjusting circuit unit with at least one circuit element;
- at least one standard circuit unit;
- at least two terminal connections coupled to the at least one adjusting circuit unit and the standard circuit unit;
