Progress on Memristor-Based Analog Logic Operation

Abstract

There is always a need for low-power, area-efficient VLSI (Very Large-Scale Integration) design and this need is increasing day by day. However, conventional design methods based on Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET) devices and Complementary Metal-Oxide-Semiconductor Transistor (CMOS) technology cannot meet the performance requirements. The memristor, as a promising computing and memory integration device, offers a new research idea for conventional logic circuit structure and architecture innovation, given its non-volatility, scalability, low power consumption, fast switching speed, etc. This paper proposes a brief overview of the characteristics and current status of memristor-based logic circuits and analyzes their applications in numerical expression and memory. The benefits and drawbacks of various analog logic circuit structures are summarized and compared. In addition, some solution strategies for these issues are presented. Finally, this paper offers prospects for the applications of memristors in the logic implementation of large-scale memristor arrays, the novel structure of in-memory computing, and neural network computing.

“…The symbol and current-voltage characteristic curve are shown in Figure 3. The characteristics of the memristor can result in a voltage divider circuit, as presented in [10][11][12][13][14], and the circuit can create OR logic and AND logic gate circuits, as shown in Figure 4. The ideal use of a memristor as a logic circuit is a passive circuit that does not require a power supply, utilizing a logic output signal generated by a voltage divider from the memristor.…”

“…In recent years, there has been a growing demand for high-performance, low-power sensing systems capable of efficiently converting analog signals from multiple sensors into a digital format for further processing [1][2][3][4][5]. Traditional approaches often rely on complex analog front-end circuits and analog-to-digital converters (ADCs), which not only consume significant power but also introduce design complexities.…”
