Abstract
A ferroelectric polarization pattern with differing feedback signals. An apparatus including a ferroelectric layer and a polarization pattern configured in the ferroelectric layer to represent position data. The polarization pattern has a first switchable polarization state domain and a second switchable polarization state domain that are both switchable by an applied signal. The first switchable polarization state domain has a first feedback signal in response to the applied signal that is different than a second feedback signal of the second switchable polarization state domain at the applied signal.
