ABSTRACT:
Input signals are weighted by weighting means composed of variable resistors, each made of an oxide thin film with a perovskite structure containing manganese, which changes resistance at room temperature according to the cumulative number of times a pulse voltage was applied and holds the resistance in a nonvolatile manner. Then, the weighted signals are inputted to an arithmetic unit. The oxide thin film used as each of the variable resistors changes its resistance, according to the cumulative number of times the input pulse was applied, and further holds the resistance in a nonvolatile manner even after the power supply is cut off. Thus, by changing the weighting factor according to the cumulative number of times the pulse voltage was applied, a neuro element more resembling a neuron of the human being is realized.
