<p>The bits of a data block are assigned to a plurality of logical groups such that at most one bit corresponding to a component is assigned to a logical group. This assignment ensures that a component failure may introduce at most one bit error to a logical group. Each logical group uses a single error correcting code to detect and correct bit errors. A parity bit is appended to a data block that includes a plurality of logical groups. The parity bit may be used in conjunction with the single error correcting codes to determine whether a detected error is a single bit error or a multiple bit error. If the detected error is a single bit error, the error correction codes may be used to correct the error. If the detected error is a multiple bit error, an uncorrectable error may be reported. <IMAGE></p> |
