Study of Memristor Models and Its Applications in Logic Circuits

One significant area of nanotechnology is nanoelectronics and a recent development in nanoelectronics is the discovery of the memristor, a fundamental circuit element. A memristor is essentially a nonvolatile nanoscale programmable resistor whose resistance, or memristance to be precise, is changed by applying a voltage across or current through, the device. Memristor has the potential to replace transistors in the digital circuit of upcoming days. Research is in full swing to find the compatibility of this device with existing CMOS technology. Throughout this paper such possible application of the memristor is investigated through SPICE simulation. The initial goal of the paper was to simulate the device characteristics. The secondary goal was to make circuits with the device. Standardization of device model is a big problem in memristor research, which is why a comparison of various models is also presented in this work. The paper has ended with a summary of our work done and possible scopes for future work.

Novel Memristor-based Non-volatile D Latch and Flip Flop Designs

International Journal for Research in Applied Science & Engineering Technology (IJRASET), 2022

Serial devices are the fundamental building elements of all digital electronic systems with memory. The non-volatile quality of sequential devices is necessary for quick data recovery after unexpected data loss, such as an unintentional power outage, which has sparked ongoing research and development into integrating a non-volatile memristor into CMOS devices. In this article, we examine using this technique to raise the caliber of nonvolatile D-latch. One memristor, a few transfer gates, and CMOS transducers are the sole components of the proposed D-latch, which sets it apart from conventional designs. Our design minimizes the negative impact of transistor threshold loss. In addition, a variety of memristor threshold values are available with our design.

For past 180 years, circuit theory is studied with three fundamental circuit elements, the resistor, the capacitor and the inductor. The memristor (short for memory resistor) is a yet quite unknown circuit element. It was predicted from the theory arguments nearly 40 years ago, but not realized as a physical component until recently. Memristors are labelled as a significant candidates for building a better storage, higher capacity and more efficient performance.
