ABSTRACT:
A data backup apparatus includes a semiconductor memory having a plurality of areas, each area storing a value of variables. A writing unit writes a value to a plural number of areas of the memory one by one, the plural number being at least four and even. A reading unit reads the values from the plural number of areas of the memory. A coincidence determining unit determines whether more than half of values read from the plural number of areas of the memory are the same as each other. An assigning unit determines a coincidence value when it has been determined that more than half of the read values are the same, so that the coincidence value is assigned to each variable.
