Abstract: A method and system detects and corrects errors in data bits of data words stored in a system memory. Each data word includes a plurality of data bits and the method includes generating a horizontal error correcting code for each data word. Vertical error correcting codes are generated, with each vertical error correcting code being generated using a particular bit from all of the data words.
