Abstract
A method and system to ensure the integrity of data in a data-processing device, a data packet is read from a memory and checked to determine whether the data packet is an existing code word of a predefined first code, and if the data packet is an existing code word, the data packet is accepted as intact, and if the data packet is not an existing code word, at least one data block of an error-correcting second code that overlaps with the read data packet is ascertained, and an error is searched for in the data packet using the second code, and the data packet is corrected on the basis of the result of the search, and the corrected data packet is accepted as intact.
