1. An integrated non-volatile component, comprising: a surface contact with associated mating contact, a ferroelectric layer used as a conductive channel having variable conductivity and the surface contact and/or the associated mating contact are/is embodied as a rectifying contact and, as a result of an applied voltage between the surface contact and the associated mating contact, a non-volatile space charge zone forms around the surface contact and/or above the mating contact in the ferroelectric layer, wherein the surface contact is in direct contact with the ferroelectric layer; and a drain terminal and a source terminal, wherein the surface contact is configured as a control gate terminal controlling the conductivity of the conductive channel between the drain terminal and the source terminal; wherein the drain terminal and the source terminal are respectively in direct contact with the ferroelectric layer.
