Abstract

A nearly ideal subthreshold slope (SS_min ∼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 ΔV_T window during endurance cycling may be affected by interface polarization fluctuation.
