Simulation of the Magnetization Dynamics of a Single Domain BiFeO Thin Film
Yu-Ching Liao, Dmitri E. Nikonov, Sourav Dutta +4
The switching dynamics of a single-domain BiFeO thin films is investigated through combining the dynamics of polarization and Neel vector. The evolution of the ferroelectric po…
A 5T-2MTJ STT-assisted Spin Orbit Torque based Ternary Content Addressable Memory for Hardware Accelerators
Siri Narla, Piyush Kumar, Azad Naeemi
In this work, we present a novel non-volatile spin transfer torque (STT) assisted spin-orbit torque (SOT) based ternary content addressable memory (TCAM) with 5 transistors and 2 m…
Hybrid Piezoelectric-Magnetic Neurons: A Proposal for Energy-Efficient Machine Learning
William Scott, Jonathan Jeffrey, Blake Heard +5
This paper proposes a spintronic neuron structure composed of a heterostructure of magnets and a piezoelectric with a magnetic tunnel junction (MTJ). The operation of the device is…
Bipolar electric field switching of perpendicular magnetic tunnel junctions through voltage controlled exchange coupling
Delin Zhang, Mukund Bapna, Wei Jiang +10
Perpendicular magnetic tunnel junctions (p-MTJs) switched utilizing bipolar electric fields have extensive applications in energy-efficient memory and logic devices. Voltage-contro…
A Probability-Density Function Approach to Capture the Stochastic Dynamics of the Nanomagnet and Impact on Circuit Performance
Nickvash Kani, Shaloo Rakheja, Azad Naeemi
In this paper we systematically evaluate the variation in the reversal delay of a nanomagnet driven by a longitudinal spin current while under the influence of thermal noise. We th…
Materials Requirements of High-Speed and Low-Power Spin-Orbit-Torque Magnetic Random-Access Memory
Xiang Li, Shy-Jay Lin, Mahendra DC +5
As spin-orbit-torque magnetic random-access memory (SOT-MRAM) is gathering great interest as the next-generation low-power and high-speed on-chip cache memory applications, it is c…
