Error control in memory storage systems

摘要

A method includes calculating a first syndrome of a codeword read from a memory location under a first set of conditions and calculating a second syndrome of the codeword read from the memory location under a second set of conditions. The method also includes analyzing the first and second syndromes and applying one of the first and second syndromes to the codeword to find the codeword having a minimum number of errors.
