摘要：The invention relates to a method and system for correcting errors in multilevelmemories using binary BCH codes. The number of errors is estimated by analyzing thesyndrome components (5). If the number of estimated errors is one, then simpledecoding for a Hamming code is performed. Otherwise, conventional decoding of theBCH code is carried out (2,3). This avoids the computation of the error locator polynomialand its roots in the presence of only one error and, thus, reduces the average decodingcomplexity.
