Abstract
PURPOSE:A logical operation circuit, etc., are used as a fixed memory error detection circuit in order to hold a correct value in some part of the fixed memory or its outside, and the error of the fixed memory is detected by a few error detecting bits, thereby simplifying its constitution.
