ABSTRACT:
Polarization loss in ferroelectric capacitors can be prevented by consecutively applying partial switching pulses to an imprinted ferroelectric capacitor, which is able to achieve a certain polarization state and the zero polarization state simultaneously, under the condition of utilizing the bistable polarization states as memory logic. This effects an improvement in both the fatigue properties and life expectancy of ferroelectric capacitors.
