Breaking the Limits in Ternary Logic: An Ultra-Efficient Auto-Backup/Restore Nonvolatile Ternary Flip-Flop Using Negative Capacitance CNTFET Technology

Despite the advantages of ternary logic, it has suffered from excessive transistor count and limited noise margin. This work proposes an ultra-efficient nonvolatile flip-flop (FF) based on negative capacitance carbon nanotube field-effect transistors (NC-CNTFETs). By harnessing differential resistance effect in NC-CNTFETs, proposed design is similar to a conventional volatile binary FF regarding number control signals. During scheduled power gating or sudden outage, benefits auto-backup/auto-restore capability without employing any additional transistors, devices, leads zero device overhead, which breakthrough designing memory circuits. On other hand, back-to- back slave latchâ??s hysteretic behavior provides extraordinary static margin that transcends both latches. The simulation results indicate eliminating backup restore circuitries 43% improvements count, 59% saving 98% energy-saving than state-of-the-art FFs. Moreover, presents 1.5 times higher Our approach opens new doors realizing circuits systems neuromorphic applications using ferroelectric-based transistors.
