Threshold Selector and Capacitive Coupled Assist Techniques for Write Voltage Reduction in Metal–Ferroelectric–Metal Field-Effect Transistor

We propose device and circuit assist techniques to lower the ferroelectric–metal field-effect transistor (FeMFET) write voltage while lowering the effect of depolarizing field. A bipolar threshold selector (TS) is connected between the intermediate node of a FeMFET and ${V}_{\text {SS}}$ , which provides a low-impedance bypass...
