PURPOSE:To enable an element to display a multi-value recording property without a complicate manufacturing process and making it subject to much restriction for a practical use by a method wherein a sweep voltage of various ranges or a pulse voltage of various volts is applied to an element of an MIM structure where an organic insulating layer is pinched between a pair of electrodes. CONSTITUTION:An element of an MIM structure is composed of, for instance, a substrate 2, a lower electrode 9, an upper electrode 8, and a molecular laminated film layer 10. When a sweep voltage of various ranges or a pulse voltage of various volts is applied to the element, it is preferable that the voltage is within the range of + or -30V. And, the pulse voltage applied for 10nsec-1sec is adequate, and it is more preferable that it is applied for 100nsec-1sec. The MIM structure element of this design is made to display a non-linear type current voltage characteristic different from a conventional one by applying the above voltage. That is, the element shows three or more conductivities corresponding to various applied voltages, and the conductivities are possessed of a memorable property. |
