Abstract
A data storage device comprising a ferroelectric layer, a perovskite structure, and at least one sensor, where the perovskite structure has a polarity discontinuity configured to generate capacitance voltages in the perovskite structure based on polarization charges of the ferroelectric material, and where the at least one sensor is configured to read the capacitance voltages from the perovskite structure.
