abstract = "The energy scalability of ultra-low power nonvolatile (NV) large-scale integration (LSI) is explored in this paper. Multithreshold computing (super/near/sub-Vt) in hybrid CMOS/magnetic tunnel junction (MTJ) circuits are investigated based on SPICE-compatible MTJ model and fully depleted silicon on insulator (FD-SOI) devices. Ultra-low supply voltage operation bottlenecks associated with performance loss, parametric variations and function failure are studied in differential pair-based sensing circuit, MTJ writing/control circuit and other building blocks. A case study is performed with three typical NV-IP-ops (NV-FF), which are implemented with 28nm FD-SOI low Vt (LVT) device and forward back-bias. Results show that MTJ writing/control circuit must operate at nominal supply (super-Vt) region to guarantee MTJ switching; sensing circuit is configured with nearVt operation (0.6V) with robustness consideration, whereas other parts could be implemented with near/sub-Vt computing to achieve ultra-low power consumption and energy efficient operations.",
