Abstract
PURPOSE: To make it possible to preserve input data right before the occurrence of abnormality by storing the same data in not less than three memory elements in sequence by overlapping.
CONSTITUTION: In three groups of power-backed-up memory elements (201;202), (203;204) and (205;206), the same data are written 21 in sequence and stored 20 by overlapping and on the basis of a difference among three pieces of memory information generated due to the break of power, information right before calculating operation stops due to the power failure is detected 22 in power recovery. When the output is sent out to data processing part 24, the input data are written in memory part 20 at data transmission timing 23 by exercising control 23 over write part 21. Consequently, even when one word or two words are equivalent to one piece of information, information right before the computer stops operating can be preserved.
