In recent years, as the demand for memory storage in portable electronic devices and data centers continues to expand, innovative solutions to improve storage performance have received much research attention. Among them, negative-capacitance field-effect transistors (NCFETs) have received much attention as a solution to improve memory performance. NCFETs use ferroelectric materials as the capacitive layer in the transistor to operate the charge carriers in the channel by implementing negative-capacitance behavior. It has been demonstrated that the negative capacitance behavior of NCFETs can improve memory performance in terms of speed, stability, and endurance. This paper provides a comprehensive review of NCFET research in electronics, including the fundamentals, materials used, recent advances, and applications in digital and analog integrated circuits. Finally, the article explores the challenges and potential solutions for implementing NCFETs in storage technology.
