Abstract

This paper proposes a new reconfigurable logic circuits based on InGaZnO resistive random-access memory (ReRAM) and presents a comprehensive investigation of their electrical characteristics and logic operation. Two fundamental equations that govern the transport mechanism of oxygen ions were utilized to model the formation of lateral and vertical conducting filaments in ReRAM devices in a circuit simulation environment. Based on the device models, the electrical behavior of ReRAM was examined and verified, using circuit simulators. Experimental results from dc current–voltage and pulse measurements of ReRAM and thin-film transistors (TFTs) demonstrate their electrical switching characteristics. The paper analyzes and validates the operation of two ReRAM-based logic configurations: 1 T-1 M (one transistor and one ReRAM cell) and 2 T-2 M−INV (inverter). A detailed analysis were conducted to compare the proposed ReRAM-based logic with the conventional CMOS counterparts, revealing favorable advantages in reducing transistor counts and die areas. The 1 T-1 M and 2 T-2 M−INV exhibit reconfigurable logic operations under different resistive states of ReRAM cells. Additionally, the investigations of short-circuit current profiles shows the superior performance of ReRAM-based logic gates to the CMOS counterpart in terms of power consumption. Overall, this study investigates the feasibility of ReRAM-based reconfigurable logic circuits for future low-power and high-performance computing applications.
集成非晶InGaZnO ReRAM和薄膜晶体管的可重构逻辑门研究
本文提出了一种基于InGaZnO阻性随机存取存储器(ReRAM)的可重构逻辑电路,并对其电学特性和逻辑运算进行了全面的研究。在电路仿真环境中,利用控制氧离子传输机制的两个基本方程来模拟ReRAM器件中横向和垂直导电丝的形成。在器件模型的基础上,利用电路模拟器对ReRAM的电学行为进行了测试和验证。对ReRAM和薄膜晶体管(TFTs)的直流电压和脉冲测量的实验结果证明了它们的电开关特性。本文分析并验证了两种基于ReRAM的逻辑配置的操作:1 t - 1m(一个晶体管和一个ReRAM单元)和2 t - 2m−INV(逆变器)。详细分析了所提出的基于reram的逻辑与传统CMOS对应逻辑的比较,揭示了在减少晶体管数量和芯片面积方面的有利优势。1 T-1 M和2 T-2 M−INV在不同的ReRAM单元电阻状态下表现出可重构的逻辑运算。此外,对短路电流曲线的研究表明,基于reram的逻辑门在功耗方面优于CMOS对应物。总体而言,本研究探讨了基于reram的可重构逻辑电路在未来低功耗和高性能计算应用中的可行性。
