Abstract Ferroelectric memory is a promising candidate for next‐generation nonvolatile owing to its outstanding performance such as low power consumption, fast speed, and high endurance. However, the ferroelectricity of conventional ferroelectric materials will be eliminated by depolarization field when size drops nanometer scale.
