PURPOSE:To detect signals before stored data becomes incapable of being used by providing a retry control means to decide how many times retry was executed at the time of the write and the read of the data. CONSTITUTION:The retry control means 4 stores the number of times of write or read processing on the basis of the error output information of a write/read means 3. Further, it decides whether the number of times of the retry reaches the number of times of the retry to output an error held in the inside of not. As the result, if it does not reach the number of times of the retry, it repeats prescribed processing, and if it reaches the number of times of the retry, it outputs retry processing finish information. An outputting means 5 outputs the number of times together with the message of the purport of a retry error on the basis of the retry processing finish information of the control means 4, and finishes the processing. Thus, the signals can be grasped before the data becomes incapable of being used, and a countermeasure can be taken beforehand. |
