THIS INVENTION RELATES TO AN INFORMATION PROCESSING METHOD AND APPARATUS. A MEMORY FOR STORING INFORMATION IN BLOCK UNITS, COMPRISES A DATA REGION FOR STORING DATA IN BLOCK UNITS AND A FIRST AND A SECOND REGION FOR STORING PLURAL BLOCK NUMBERS WHICH ARE NUMBERS ASSIGNED TO BLOCKS IN A DATA REGION. DATA IS WRITTEN TO A BLOCK OF THE DATA REGION CORRESPONDING TO A BLOCK NUMBER STORED IN ONE OF THE FIRST AND SECOND REGIONS, THE BLOCK NUMBER OF THE BLOCK TO WHICH DATA WAS WRITTEN IS STORED IN THE OTHER OF THE FIRST AND SECOND REGIONS, AND THE DATA IN THE ONE OF THE FIRST AND SECOND REGIONS IS ERASED. IN THIS WAY, THERE IS LESS RISK OF MEMORY CORRUPTION, AND DATA CAN BE READ STABLY.(FIG. 7) |
