Zusammenfassung: | The present invention relates to a method and circuit arrangement for performing an error correction in a memory arrangement in which a redundancy system is used. The addresses of faulty cells are recorded redundantly by applying a corresponding coding. Then, an error correction is applied to the faulty-address information before it is compared to an externally applied address. Thereby, errors due to faulty redundancy addresses can be prevented. |
