Special Issue Information

Dear Colleagues,

Since the start of the fourth industrial revolution, neural process-based artificial intelligence and internet of things have rapidly increased the demand for data processing. Modern computing systems have encountered a “bottleneck” and high-power consumption due to a number of the sequential data processing. In this context, a novel design of computing architectures (or system) based on memristors have shown excellent potential in replacing conventional computing systems and the emergence of new hardware such as memristors is a necessary and interest and efforts in related research are needed.

However, there are several challenges to using memristors in computing systems. In this Special Issue, we focus on memristors. In addition, recent demonstrations of novel models of the computing and integration using memristors are surveyed.

Considering this situation, the aim of this Special Issue is to gather the most recent research and structural developments of memristors for models, developments, and applications, including the following topics:

  • Electrical characteristics for memristors;
  • Nanomaterials and nanocomposites for memristors;
  • Two-dimensional structures for memristors;
  • Crossbar array of memristors;
  • Neuromorphic-behaving memristors;
  • Integration and neuromorphic computing system based on memristors;
  • Low-power consumption of memristors.

Extracting behavioral models of RRAM devices is challenging due to their unique “memory” behaviors and rapid developments, for which well-established modeling frameworks and systematic parameter extraction processes are not available. In this work, we propose a physics-informed recurrent neural network (PiRNN) methodology to generate behavioral models of RRAM devices from practical measurement/simulation data. The proposed framework can faithfully capture the evolution of internal state and its impacts on the output. A series of modifications informed by the RRAM device physics are proposed to enhance the modeling capabilities. The integration strategy of Verilog-A equivalent circuits, is also developed for compatibility with existing general-purpose circuit simulators. The Verilog-A model can be easily adopted into the SPICE-type simulator for the circuit design with a variable step that differs from the training process. Numerical experiments with real RRAM devices data demonstrate the feasibility and advantages of the proposed methodology. Full article

The memristor, characterized by its nano-size, nonvolatility, and continuously adjustable resistance, is a promising candidate for constructing brain-inspired computing. It operates based on ion migration, enabling it to store and retrieve electrical charges. This paper reviews current research on synapses using digital and analog memristors. Synapses based on digital memristors have been utilized to construct positive, zero, and negative weights for artificial neural networks, while synapses based on analog memristors have demonstrated their ability to simulate the essential functions of neural synapses, such as short-term memory (STM), long-term memory (LTM), spike-timing-dependent plasticity (STDP), spike-rate-dependent plasticity (SRDP), and paired-pulse facilitation (PPF). Furthermore, synapses based on analog memristors have shown potential for performing advanced functions such as experiential learning, associative learning, and nonassociative learning. Finally, we highlight some challenges of building large-scale artificial neural networks using memristors. Full article
