Introduction to neuromorphic functions of memristors: 

The inductive nature of synapse potentiation

J. Appl. Phys. 21 March 2025; 137 (11): 111101

DOI: 10.1063/5.0257462

Abstract: Memristors are key elements for building synapses and neurons in advanced neuromorphic computation. Memristors are made with a wide range of material technologies, but they share some basic functionalities to reproduce biological functions such as synapse plasticity for dynamic information processing. Here, we explain the basic neuromorphic functions of memristors, and we show that the main memristor functionalities can be obtained with a combination of ordinary two-contact circuit elements: inductors, capacitors, resistors, and rectifiers. The measured IV characteristics of the circuit yield clockwise and counterclockwise loops, which are like those obtained from memristors. The inductor is responsible for the set of resistive switching, while the capacitor produces a reset cycle. By combining inductive and capacitive properties with gating variables represented by diodes, we can construct the full potentiation and depression responses of a synapse against applied trains of voltage pulses of different polarities. These results facilitate identifying the central dynamical characteristic required in the investigation of synaptic memristors.

[paper] Benchmarks for SPICE AI/ML Modeling

Benchmarks for SPICE Modeling and Parameter Extraction Based on AI/ML

Abstract: Over the past decades, the number of submitted articles that use numerical approaches for SPICE models or for characterization (extraction) of parameters of existing SPICE models has grown significantly. Many of those articles rely on synthetic data, generated either from technology computer-aided design (TCAD) or from physical SPICE model simulations; most do not model/fit measured data. Furthermore, those articles do not evaluate the physical correctness, smoothness/monotonicity, or asymptotic correctness of the approach they propose. That is sufficient for initial evaluation of proposed techniques. However, it does not prove that they are “industrial strength.” This article presents benchmarks/guidelines for the proposed artificial intelligence (AI)/machine learning (ML) SPICE modeling and characterization techniques to try to help them become practical and useful.
