Abstract
PURPOSE: To make program modification possible by additional wirting to a memory by detecting an error by cylically adding memory addresses on a fixed system.
CONSTITUTION: Contents A and B at memory addresses are cyclically added on the basis of formula I to obtain result Z and depending upon whether the result Z is equal to a fixed value, a decision on an error is made, so that even if there is no memory data, an influence upon the arithmetic result will never be exerted. Therefore, additional writing to the memory makes it possible to modify a program and operation for the program modification is simplified.
