Abstract

In illustrative embodiments disclosed herein, a logic element may be provided on the basis of a non-volatile storage mechanism, such as ferroelectric transistor elements, wherein the functional behavior may be adjusted or programmed on the basis of a shift of threshold voltages. To this end, a P-type transistor element and an N-type transistor element may be connected in parallel, while a ferroelectric material may be used so as to establish a first polarization state resulting in a first functional behavior and a second polarization state resulting in a second different functional behavior. For example, the logic element may enable a switching between P-type transistor behavior and N-type transistor behavior depending on the polarization state.
