Abstract
An electrical resistor element, system, and method related thereto, wherein the electrical resistor element includes a tunable resistance. The electrical resistor element comprises a first contact electrode, a second contact electrode and a ferroelectric layer arranged between the first contact electrode and the second contact electrode. The ferroelectric layer comprises a first area having a first polarization direction and a second area having a second polarization direction. The first polarization direction is different to the second polarization direction. The ferroelectric layer further comprises a domain wall between the first area and the second area. The electrical resistor element further comprises a first pinning element configured to stabilize the first polarization direction of the ferroelectric layer. The electrical resistor element further comprises a control circuit configured to tune the resistance of the electrical resistor element by applying electrical pulses to the ferroelectric layer such that the ferroelectric domain wall is moved.
