  • Abstract
    A nearly ideal subthreshold slope (SSmin ~58mV/dec) and an ultralow off-state current of 10-14A/μm have been demonstrated in HfZrO ferroelectric memory. The interface states with slow relaxation time seemingly shows no significant impact for nanosecond ferroelectric switching, but output ΔVT window during endurance cycling may be affected by interface polarization fluctuation.
