A method for automatically detecting and correcting memory errors in a secure multichannel railway computer provides each channel with at least one memory and the same data stored in parallel in the memories. A first check value is calculated for data in a subregion of the first memory and a second check value is calculated for the same data in a subregion of the second memory. First and second check values are compared and if different, first and/or second check values are compared with an old check value. Data in the subregion of the first memory are replaced by data in the subregion of the second memory if the second check value corresponds to the old check value. Data in the subregion of the second memory are replaced by data in the subregion of the first memory if the first check value corresponds to the old check value.
