Abstract
In a method for repairing a memory component, data retention times of regular memory cells are determined. Weak regular memory cells having a data retention time that is shorter than a predetermined limit value are determined. A device is programmed in such a manner that a write or read access to the weak regular memory cell is simultaneously also effected for a redundant memory cell in order to jointly read from, or write to, the weak regular memory cell and the redundant memory cell.
