Advancing Nonvolatile Computing With Nonvolatile NCFET Latches and Flip-Flops

IEEE Transactions on Circuits and Systems I: Regular Papers, 2017
Nonvolatile computing has been proven to be effective in dealing with power supply outages for on-chip check-pointing in emerging energy-harvesting Internet-of-Things applications. It also plays an important role in power-gating to cut off leakage power for higher energy efficiency. However, existing on-chip state backup solutions for D flip–flop (DFF)

Advanced Modeling and Simulation of Multilayer Spin–Transfer Torque Magnetoresistive Random Access Memory with Interface Exchange Coupling

Micromachines
In advancing the study of magnetization dynamics in STT-MRAM devices, we employ the spin drift–diffusion model to address the back-hopping effect. This issue manifests as unwanted switching either in the composite free layer or in the reference layer in ...

Laser‐Induced Ultrafast Magnetic Phase Transition in 2D Van Der Waals Antiferromagnetic Heterostructures

Advanced Science, EarlyView.
In this work, ultrafast laser‐induced spin transfer and spin relaxation dynamics in 2D van der Waals antiferromagnetic CrI3/CrGeTe3 heterostructures are investigated. Laser excitation is demonstrated to induce pronounced interlayer nonequilibrium spin dynamics and ultrafast magnetic moment reconstruction, driving a transition from an antiferromagnetic (

A multilevel nonvolatile magnetoelectric memory

Scientific Reports, 2016
AbstractThe coexistence and coupling between magnetization and electric polarization in multiferroic materials provide extra degrees of freedom for creating next-generation memory devices. A variety of concepts of multiferroic or magnetoelectric memories have been proposed and explored in the past decade.

Low‐Voltage and High‐k Properties of Bilayer HZO Capacitors at the Morphotropic Phase Boundary for Next‐Generation Memory Applications

Advanced Science, EarlyView.
The HfxZr1‐xO2‐based ferroelectric/antiferroelectric bilayer capacitor exhibits morphotropic‐phase‐boundary behavior with a high dielectric constant (∼52) at 2 V. Phase engineering stabilizes o/t‐phase coexistence and suppresses m‐phase formation, enabling capacitance enhancement and self‐optimization under cycling for scalable low‐voltage, high‐κ ...

Evaporation‐Driven Solutal Marangoni Control of Rayleigh–Taylor Instability in Inverted Films

Advanced Science, EarlyView.
Inverted liquid films, like paint on a ceiling, are inherently unstable under gravity. This work shows that selective evaporation in volatile binary mixtures generates solutal Marangoni stresses that either suppress or amplify the Rayleigh Taylor instability.
