Special Issue Information

Dear Colleagues,

In collaboration with the Journal of Low Power Electronics and Applications, we are bringing together a selected group of international experts to contribute to a Special Issue on “Memristive Neuromorphics: Neuronal Emulators and Hardware Implementations of Neural Algorithms”.

Many neuroscientists believe that brains differ from conventional computers in ways that exacerbate the dependence of algorithms on hardware. It is absurdly difficult, if not impossible, to understand cognition without considering its implementations. Fourteen years ago, HP Labs claimed the discovery of the memristor device, which has been regarded as one of the most appropriate neuromorphs for brain-inspired computing and bio-explainable artificial intelligence. Despite the enormous research interest in memristive neuromorphics and the many significant advances in this field, most observers would judge today’s memristive neuromorphic devices and circuits as still being in their infancy and lacking the sophistication and flexibility of their biological counterparts.

In this context, this Special Issue aims to bring together researchers working in directions including, but not limited to:

  • Novel neuromorphic devices with new operating principles (not just new materials) that serve as the more compact and bio-realistic embodiments of neuronal elements.
  • Novel neuromorphic devices or circuits for mimicking neuronal behaviors, especially those with a certain dynamic complexity.
  • Novel neuromorphic devices or circuits for implementing neural algorithms beyond vector‐matrix multiplication.
  • Device/circuit properties-inspired algorithms and their simulations or hardware implementations.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Low Power Electronics and Applications is an international peer-reviewed open access quarterly journal published by MDPI.

We present a transfer learning method inspired by modulatory neurotransmitter mechanisms in biological brains and explore applications for neuromorphic hardware. In this method, the pre-trained weights of an artificial neural network are held constant and a new, similar task is learned by manipulating the firing sensitivity of each neuron via a supplemental bias input. We refer to this as neuromodulatory tuning (NT). We demonstrate empirically that neuromodulatory tuning produces results comparable with traditional fine-tuning (TFT) methods in the domain of image recognition in both feed-forward deep learning and spiking neural network architectures. In our tests, NT reduced the number of parameters to be trained by four orders of magnitude as compared with traditional fine-tuning methods. We further demonstrate that neuromodulatory tuning can be implemented in analog hardware as a current source with a variable supply voltage. Our analog neuron design implements the leaky integrate-and-fire model with three bi-directional binary-scaled current sources comprising the synapse. Signals approximating modulatory neurotransmitter mechanisms are applied via adjustable power domains associated with each synapse. We validate the feasibility of the circuit design using high-fidelity simulation tools and propose an efficient implementation of neuromodulatory tuning using integrated analog circuits that consume significantly less power than digital hardware (GPU/CPU).

Memristive neuromorphic systems represent one of the most promising technologies to overcome the current challenges faced by conventional computer systems. They have recently been proposed for a wide variety of applications, such as nonvolatile computer memory, neuroprosthetics, and brain–machine interfaces. However, due to their intrinsically nonlinear characteristics, they present a very complex dynamic behavior, including self-sustained oscillations, seizure-like events, and chaos, which may compromise their use in closed-loop systems. In this work, a novel intelligent controller is proposed to suppress seizure-like events in a memristive circuit based on the Hodgkin–Huxley equations. For this purpose, an adaptive neural network is adopted within a Lyapunov-based nonlinear control scheme to attenuate bursting dynamics in the circuit, while compensating for modeling uncertainties and external disturbances. The boundedness and convergence properties of the proposed control scheme are rigorously proved by means of a Lyapunov-like stability analysis. The obtained results confirm the effectiveness of the proposed intelligent controller, presenting a much improved performance when compared with a conventional nonlinear control scheme. Full article

In this study, a direct-grown helical-shaped tungsten-oxide-based (h-WOx) selection device is presented for emerging memory applications. The selectivity in the selection devices is from 10 to 103 with a low off-current of 0.1 to 0.01 nA. In addition, the selectivity of volatile switching in the h-WOx selection devices is reconfigurable with a pseudo RESET process on the one-time negative voltage operations. The helical-shaped selection devices with the glancing angle deposition (GLAD) method show good compatibility, low power consumption, good selectivity, and good reconfigurability for next-generation memory applications.
