Abstract:
A method for operating a network using a bidirectional memory cell means that stores an analog memory record of a sensitivity, said bidirectional memory cell means being connected to one of a value of an input variable means and a one of a value of an input co-variable means, and one of a value of an output variable means and one of a value of an output co-variable means, uniquely, said method of said bidirectional memory cell means comprising:a. allowing said bidirectional memory cell means to make a forward-selection of a forward-selected value of said output variable means, andb. making said forward selection by a forward-selecting bidirectional memory cell means, said forward-selecting bidirectional memory cell means being connected to an extant value of said input variable means and said forward-selected value of said output variable means, said forward-selection being made when a forward-selecting voltage ramp means reaches a required voltage level determined by an extant value of said sensitivity, andc. making a reduction is said sensitivity of said forward-selecting bidirectional memory cell means, said reduction being equal to said extant value of said sensitivity multiplied by a predetermined constant, said predetermined constant being in a range from one to a value greater than zero, andd. prohibiting said forward-selection of another value of said output variable means, ande. allowing said bidirectional memory cell means to make a back-selection of a back-selected value of said input co-variable means, andf. making said back-selection by a back-selecting bidirectional memory cell means, said back-selecting bidirectional memory cell means being connected to an extant value of said output co-variable means and said back-selected value of said input co-variable means, said back-selection being made when a back-selecting voltage ramp means reaches said required voltage level determined by said extant value of said sensitivity, andg. making an increase is said sensitivity of said back-selecting bidirectional memory cell means, said increase being equal to a difference between a maximum sensitivity and said extant value of said sensitivity, said difference being multiplied by a predetermined constant, said predetermined constant being in a range from one to a value greater than zero, andh. prohibiting said back-selection of another value of said input co-variable means, whereini. said sensitivity of said bidirectional memory cell means is determined by a number of times said increase is made in relation to a number of times said decrease is made, wherebyj. said bidirectional memory cell means is useful in a network of a self-learning unit means.
