Energy-efficient switching of nanomagnets for computing: Straintronics and other methodologies
Noel D'Souza, Ayan Biswas, Hasnain Ahmad +7
The need for increasingly powerful computing hardware has spawned many ideas stipulating, primarily, the replacement of traditional transistors with alternate "switches" that dissi…
Experimental demonstration of complete 180 degree reversal of magnetization in isolated Co-nanomagnets on a PMN-PT substrate with voltage generated strain
Ayan Kumar Biswas, Hasnain Ahmad, Jayasimha Atulasimha +1
Rotating the magnetization of a shape anisotropic magnetostrictive nanomagnet with voltage-generated stress/strain dissipates much less energy than most other magnetization rotatio…
Image Processing with Dipole-Coupled Nanomagnets: Noise Suppression and Edge Enhancement Detection
Md Ahsanul Abeed, Ayan K. Biswas, Md Mamun Al-Rashid +2
Hardware based image processing offers speed and convenience not found in software-centric approaches. Here, we show theoretically that a two-dimensional periodic array of dipole-c…
Self-similar Magneto-electric Nanocircuit Technology for Probabilistic Inference Engines
Santosh Khasanvis, Mingyu Li, Mostafizur Rahman +5
Probabilistic graphical models are powerful mathematical formalisms for machine learning and reasoning under uncertainty that are widely used for cognitive computing. However they…
Energy-efficient hybrid spintronic-straintronic reconfigurable bit comparator
Ayan K. Biswas, Jayasimha Atulasimha, Supriyo Bandyopadhyay
We propose a reconfigurable bit comparator implemented with a nanowire spin valve whose two contacts are magnetostrictive with bistable magnetization. Reference and input bits are…
Straintronic spin-neuron
Ayan K. Biswas, Jayasimha Atulasimha, Supriyo Bandyopadhyay
In artificial neural networks, neurons are usually implemented with highly dissipative CMOS-based operational amplifiers. A more energy-efficient implementation is a 'spin-neuron'…
Reply to Comment on "Acoustically assisted spin-transfer-torque switching of nanomagnets: An energy-efficient hybrid writing scheme for non-volatile memory" [Appl. Phys. Lett., 103, 232401 (2013)]
Ayan Kumar Biswas, Jayasimha Atulasimha, Supriyo Bandyopadhyay
This is a reply to a comment on our work recently posted in arXiv. To our knowledge, this comment has not been published anywhere else. We show that the points raised in the commen…
Magneto-elastic universal logic gate: A non-volatile, error-resilient Boolean logic gate with ultra-low energy-delay product
Ayan K. Biswas, Jayasimha Atulasimha, Supriyo Bandyopadhyay
A long-standing goal of computer technology is to process and store digital information with the same device in order to implement new architectures. One way to accomplish this is…
Highly reliable low-energy writing of bits in non-volatile multiferroic memory based on 180-degree magnetization switching with voltage-generated stress
Ayan K. Biswas, Supriyo Bandyopadhyay, Jayasimha Atulasimha
Rotating the magnetization of a magnetostrictive nanomagnet with electrically generated mechanical strain dissipates miniscule amount of energy compared to any other rotation metho…
Energy-efficient magnetoelastic non-volatile memory
Ayan K. Biswas, Supriyo Bandyopadhyay, Jayasimha Atulasimha
We propose an improved scheme for low-power writing of binary bits in non-volatile (multiferroic) magnetic memory with electrically generated mechanical stress. Compared to an earl…
