Abstract
PURPOSE: To reduce the frequency of error production, by storing the address for error correction at memory readout, and writing corrected information in an error part at the waiting time of processing.
CONSTITUTION: Error correction code is written in together with the information in the memory 2. When information is read out from the address of the memory 2 designated with the address register 1, if error is detected, from the check of the presence of error at the error detection and correction circuit 4, then the correction of information is made at the error detection and correction circuit 4, and the address having error is stored in the error address register ER6. Further, when the memory 2 enters the waiting time such as refresh, the content of the memory 2 corrected before is read out and given to the register 5, correction is made at the error detection and correction circuit 4, and new error correction code is formed with the error correction code generating circuit 3, which is added to the corrected information and it is written in the specified address of the memory 2.
