The transient behavior of a ferroelectric PbZrxTi1−xO3 and superconducting YBa2Cu3O7−x three-terminal device has been investigated. Four-state behavior, that is, two polarization states of the PbZrxTi1−xO3 gate and superconducting and normal states of the YBa2Cu3O7−x layer, has been observed. It was shown that the biased superconducting channel can be switched from superconducting state to the normal state by the flowing charge during the polarization switching of the PbZrxTi1−xO3 gate. The nonvolatility of this device based on the different polarization states of the ferroelectric gate has also been demonstrated.
