Abstract
PURPOSE: To simplify constitution on the whole by checking an input circuit and output circuit by connecting the input and output of a data processing circuit in common.
CONSTITUTION: Write data WD0WQD7, after being lgiven parity bit P2 by parity generating circuit 4, are stored in write register 1. They are sent from register 1 to memory element 8 and parity/check circuit 9 at the same time by data write clock WCLK and while they are written in memory element 8, a parity check is made. To read data in memory element 8, read data are given parity bit P2 by parity generating circuit/check circuit 9 and then sent to read data register 3, so that a parity check will be done by parity check circuit 7. Therefore, an input-output circuit error can be detected without operating the data processing circuit.
