Abstract:
In a method of operating a ferroelectric device, a ferroelectric device including a first electrode layer, a ferroelectric layer and a second electrode layer that are sequentially disposed is provided. A first remanent polarization is written in the ferroelectric layer. An operating voltage is applied between the first and second electrode layers to write a second remanent polarization having a polarization value different from a polarization value of the first remanent polarization in the ferroelectric layer. An amplitude of the operating voltage varies within a voltage application time period and varies in a set voltage range.

Claim (Index 11):
A method of operating a ferroelectric device, the method comprising:\n providing a ferroelectric device including a first electrode layer, a ferroelectric layer and a second electrode layer that are sequentially disposed; and applying an operating voltage to the ferroelectric layer to write a predetermined remanent polarization smaller than a maximum remanent polarization in the ferroelectric layer, the operating voltage providing a second saturation electric field lower than a first saturation electric field that generates the maximum remanent polarization for the ferroelectric layer, wherein applying the operating voltage generates a new ferroelectricity hysteresis behavior comprising the predetermined remanent polarization in the ferroelectric layer.
