Background

The rapidly evolving research field of brain-inspired (neuromorphic) computing aims to address modern computing challenges, such as the memory wall problem (the limited rate of data transfer between CPU and memory), for data intensive applications in the era of artificial intelligence and internet-of-things. Neuromorphic computing has attracted strong interests due to its massive parallelism, high energy efficiency, and cognitive functions. Different types of emerging technology solutions, such as the charge-based and resistance-based memory devices, provide unique functional behaviors for emulating artificial synapses and neurons, and offer distinct design opportunities for implementing in-memory neuromorphic computing systems at circuit and architecture levels.

The research topic aims to present the recent advances of cutting-edge research and developments in emerging memory technologies with applications in brain-inspired neuromorphic computing. The research topic focuses on the functional potential of diverse memory devices to emulate various functions of biological synapses and neurons for in-memory computing. More specifically, this research topic’s interests include the simulation or experimental implementation of different brain-inspired primitives, circuits, computing systems, and neural networks. The innovations of advanced memory devices for neuromorphic applications are also within the scope of the research topic. Exploring the highly efficient realizations of artificial neurons and synapses, and their integration at the circuit and architecture levels is critical to the development of highly efficient future neuromorphic systems.

We invite manuscripts reporting novel research results (experimental, numerical, and theoretical) on neuromorphic computing with emerging memory devices. To this purpose, we welcome articles addressing (but not limited to) the following:

- Novel fabrication techniques for memory devices to facilitate neuromorphic system implementation, insights on variability and endurance limits of memory devices for neuromorphic circuits/systems and new insights on the design challenges in memory device based neuromorphic systems
- Design of artificial synaptic and neural primitives utilizing charge-based memory devices and resistance-based memory devices, for example, Resistive Random-Access Memory (ReRAM), Phase Change Memory (PCM), Spin Transfer Torque Magneto Resistive Random-Access Memory (STT-MRAM), Ferroelectric Field Effect Transistor (FeFET), Ferroelectric Tunnel Junction (FTJ), etc.
- Novel computing systems leveraging emerging memory device properties and device-circuit-architecture-algorithm co-design with emerging memory technologies.
- We also solicit reviews of hardware-related neuromorphic implementations, perspectives on the nature, past, present, and future of neuromorphic implementations and constructive commentaries on specific papers or pieces of work.

Keywords: Neuromorphic computing, neural networks, resistance-based memory devices, charge-based memory devices, artificial neurons, artificial synapses, in-memory computing

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
