Metal–ferroelectric–semiconductor field-effect-transistors (MFS-FETs) with the Ag/Bi<jats:sub>4</jats:sub>Ti<jats:sub>3</jats:sub>O<jats:sub>12</jats:sub>/p-Si (100) structures were fabricated. The <jats:italic>I</jats:italic>
<jats:sub>ds</jats:sub>–<jats:italic>V</jats:italic>
<jats:sub>g</jats:sub> hysteresis curve of the FET shows the counter-clockwise direction, which demonstrates the charge of channel conductivity due to the ferroelectric polarization of Bi<jats:sub>4</jats:sub>Ti<jats:sub>3</jats:sub>O<jats:sub>12</jats:sub> and the memory window with a gate voltage of ±6 V was 1.2 V. The current ratio of <jats:italic>I</jats:italic>
<jats:sub>ds(on)</jats:sub> to <jats:italic>I</jats:italic>
<jats:sub>ds(off)</jats:sub> was over two orders in magnitude at zero gate voltage which indicates the MFS-FET can be used in nondestructive readout (NDRO) applications.
