ABSTRACT:
A faulty-memory processing method and apparatus in a data processing system which executes a time-sharing data process with breaks. Hard error which may exist in a cell in a normal memory is detected by using an error correction circuit. After correcting an error in information read out from a detected hard-error cell in the normal memory, information including the above corrected information with respect to the detected hard-error cell is transcribed into a relief memory. The above correction and transcription is executed during the breaks in the time-sharing data process.
