“…As a consequence, spins in the opposite direction of the magnet will accumulate in the channel. Meanwhile, only the spins in the same direction as M1 will pass out of M1, while the spins in the opposite direction will move through the channel to switch the direction of M2, so the device will work as an inverter [67]. Based on this phenomena, one leverages the Current-In-Plane non-local spin valve modular model in [68] to simulate the all-spin logic.…”

Abstract:In this review article for Internet of Things (IoT) applications, important low-power design techniques for digital and mixed-signal analog-digital converter (ADC) circuits are presented. Emerging low voltage logic devices and non-volatile memories (NVMs) beyond CMOS are illustrated. In addition, energy-constrained hardware security issues are reviewed. Specifically, light-weight encryption-based correlational power analysis, successive approximation register (SAR) ADC security using tunnel field effect transistors (FETs), logic obfuscation using silicon nanowire FETs, and all-spin logic devices are highlighted. Furthermore, a novel ultra-low power design using bio-inspired neuromorphic computing and spiking neural network security are discussed.

Abstract-Manipulating logic functions via majority operators recently drew the attention of researchers in computer science. For example, circuit optimization based on majority operators enables superior results as compared to traditional synthesis tools. Also, the Boolean satisfiability problem finds new solution approaches when described in terms of majority decisions. To support computer logic applications based on majority, a sound and complete set of axioms is required. Most of the recent advances in majority logic deal only with ternary majority (MAJ-3) operators because the axiomatization with solely MAJ-3 and complementation operators is well understood. However, it is of interest extending such axiomatization to n-ary majority operators (MAJ-n) from both the theoretical and practical perspective. In this work, we address this issue by introducing a sound and complete axiomatization of MAJ-n logic. Our axiomatization naturally includes existing MAJ-3 and MAJ-5 axiomatic systems. Based on this general set of axioms, computer applications can now fully exploit the expressive power of majority logic.

“…Recent advances in spintronics, especially experiments showing the switching of nano-magnets with spin polarized current, has led to the possibility of very high density on-chip magnetic storage with zero leakage power, and logic styles that can potentially have very low intrinsic power consumption [1]- [3]. Most of the nano-magnetic devices use magnetic tunnel junctions (MTJs) or spin-valves [5] to efficiently write/read the magnets.…”

A simulation framework that can comprehend the impact of material changes at the device level to the system level design can be of great value, especially to evaluate the impact of emerging devices on various applications. To that effect, we have developed a SPICE-based hybrid MTJ/CMOS (magnetic tunnel junction) simulator, which can be used to explore new opportunities in large scale system design. In the proposed simulation framework, MTJ modeling is based on LandauLifshitz-Gilbert (LLG) equation, incorporating both spin-torque and external magnetic field(s). LLG along with heat diffusion equation, thermal variations, and electron transport are implemented using SPICE-inbuilt voltage dependent current sources and capacitors. The proposed simulation framework is flexible since the device dimensions such as MgO thickness and area, are user defined parameters. Furthermore, we have benchmarked this model with experiments in terms of switching current density (J C ), switching time (T SWITCH ) and tunneling magneto-resistance (TMR). Finally, we used our framework to simulate STT-MRAMs and magnetic flip-flops (MFF).
