Vertical Ferroelectric HfO<inf>2</inf> FET based on 3-D NAND Architecture: Towards Dense Low-Power Memory

A vertical ferroelectric HfO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> field effect transistor based on 3-D macaroni NAND architecture is reported for the first time. Up to 2 V memory window was obtained after the application of 100 ns program/erase pulses. Flash-like endurance of 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sup> cycles is reported and first reliability assessments were performed.
