Invited talk by Sonal Shreya

Abstract:

This talk will explore the importance and features of Spintronic Devices, as well as their potential for various applications. At first, I will present how to bridge the gap between a device-to-circuit-to-system level design which is very essential in the current scenario wherein emerging devices are defining the possibilities for several applications (such as cognitive or neuromorphic computing, neurotechnology, image/signal recognition, and so on). Compact analytical device modeling is the key that provides the device’s behavioral characteristics in the form of electrical symbols/modules. The model can easily be incorporated in circuit simulators for circuit-to-system level designs along with the benefit of device-level monitoring. It enables the circuit designers to use the electrical device symbol with fully developed CMOS counterparts in IC design. I will discuss the device modeling step-by-step of voltage-controlled spin-orbit torque (VCSOT) with multibit storage and spin-torque nano oscillator. The device model considered the thermal stability and temperature variability effects as well, henceforth, making the device model more robust for circuit designing. Furthermore, consideration is given to the circuit-level design of in-memory computing, the diode, as well as neuronal and synaptic functions. Additionally, this talk discusses several aspects of spintronic devices that make them a potential alternative for the future of semiconductor electronics for applications such as Artificial Intelligence, Neuromorphic Computing, the Internet of Things, and Biomedical.
