Abstract
To check the useful data of a read-write memory, subsets of the data are formed from the total quantity of useful data, and error-correction data are calculated for each subset of useful data. The subsets of useful data and the corresponding error-correction data are transmitted block-by-block to the read-write memory. During each reading operation, the block containing the desired useful data is read out and the integrity of that data is checked with the aid of the error-correction data.
