Abstract

PURPOSE: To make it possible to distinguish between a parity error and memory fault securely by displaying the parity error and uncorrectable error respectively.
CONSTITUTION: Between a main body, e.g. CPU5 and memory controller 6, an interface on a parity bit system is arranged and controller 6, when an error of write data or a parity bit is detected, writes an uncorrectable error code in memory 7. Then, when parity checking circuit 11 of controller 6 makes a check and the parity error is found, it is displayed on display circuit 15. When detected by error detecting-correcting circuit 13, the uncorrectable error is displayed on display circuit 16. Thus, it is made possible to discriminate securely whether the uncorrectable error is caused by the parity error or memory fault.
