Whenever there is limited input/output signals available, data integrity can be maintained, according to the present technique, by utilizing a single parity bit. By encoding command signals uniquely, a single parity bit can be made to achieve the following characteristics: 1) The command bus and the output data bus are parity checked as one entity. 2) On WRITE commands, the parity bit indicates also the parity for the output data.
