Abstract: PROBLEM TO BE SOLVED: To provide a method for storing a membership function for easily and economically deciding the crossing of the membership function with an input. SOLUTION: This method for storing a membership function includes the storing of a position CV in an universe of discourse UdD of the vertex of a triangle normalizing the membership function, and the storing of a first distance LVD between the cross point of the left side of the triangle with the axis of the universe of discourse and the position CV of the vertex. Moreover, this method includes the storing of a second distance RVD between the cross point of the right side of the triangle with the axis of the universe of discourse and the position CV of the vertex. Moreover, in a circuit which calculates the assignment of the data of the antecedent part of a fuzzy rule, an input variable can be made fuzzy by using a geometrical ratio generated among the similar corresponding sides of the triangle normalized by the position of an input value in the universe of discourse.
