ABSTRACT:
An integrated circuit, in particular, an integrated memory, contains a control circuit for ascertaining an operating state of the circuit. A self-repair circuit, which is connected to the control circuit, is used to implement self-test and self-repair operation for checking the functioning of, and repairing, defective circuit sections of the integrated circuit. After a supply voltage has been applied to the integrated circuit, the control circuit ascertains an operating state of the integrated circuit and, in a manner dependent thereon, the self-repair circuit is activated by the control circuit in a self-controlling manner in order to put the integrated circuit into a self-repair mode for implementing self-test and self-repair operation. The integrated circuit can be tested for its functionality and repaired even after being soldered onto a module substrate.
