Abstract

The inventive method uses at least partial redundancy of a protected storage capacity and a Hamming error correction code. Said method consists in storing encoded data which contains useful data bits and correction data bits, encoded data being obtained by multiplying the useful data by a correction matrix obtainable from a generating matrix, and in carrying out a periodical background job in order to check data accuracy by multiplying encoded data by transposing the correction matrix, and in the event that the multiplication product is not zero because of an error on at least one bit, in correcting the entire part of errors on the stored erasable data with the aid of information supplied by the multiplication result giving the position of erroneous bites. Said invention can be used for the control computer of an electric power steering system.
