Abstract

A tunable resistive element includes a first terminal, a second terminal and a resistive layer having a tunable resistive material. The resistive layer is arranged between the first terminal and the second terminal. The resistive element further includes a piezoelectric layer having a piezoelectric material. The piezoelectric layer is adapted to apply stress to the resistive layer. An electrical resistance of the tunable resistive material is dependent upon a first electrical control signal applied to the first terminal and the second terminal as well as upon the stress applied by the piezoelectric layer to the resistive layer. The stress applied by the piezoelectric layer is dependent on a second electrical control signal applied to the piezoelectric layer.
