Patent attributes
A memory device is provided that includes at least one resistive memory cell, a negative capacitance field effect transistor (NC-FET) serving as a voltage amplifier, and a switch enable circuit connecting NC-FET to the memory cell. The NC-FET includes a regular FET having a metal gate terminal and a ferroelectric capacitor. The NC-FET gate terminal forms one plate of the ferroelectric (FE) capacitor. The ferroelectric capacitor includes a ferroelectric dielectric material deposited between a formed upper gate conductive contact and he metal gate terminal. To provide further flexibility, a metal layer can be deposited before the deposition of the ferroelectric material to form a MIM-like FE capacitor so that the capacitance of FE capacitance can be independently tuned by choosing the right height (H), width (W), and length (L) to achieve desired matching between |C
