A Versatile Memristor Circuit Emulator for Nanoscale Thin-film TiO2 Using Discrete-electronic Components

Abstract

Extended Abstract The successful fabrication of a real nanoscale thin-film TiO2 memristor from Hewlett Packard (HP) Laboratories has greatly re-energized the interests of researcher in memristor and its future promising applications, especially in nanoscale era because of the limitations in CMOS technology [1]. Many works have started to utilized memristor in diverse nanoscale areas; especially non-volatile random access memory (ReRAM) and neuronmophic synaptic networks [2]. However, the solid memristor devices are not expected to be available in the near future because of the technical difficulties involved in the nanoscale fabrications. Therefore, a replacement which behaves like a real memristor device is urgently needed to allow researchers to study the practical application of memristors. In this study, we present a memristor emulator circuit which can correctly mimic the behaviour of the real nanoscale TiO2 thin-film memristor device from HP Labs. Additionally, the proposed emulator can also show various i-v hysteresis characteristics as observed at different dimensions of real memristor devices. The proposed emulator is a flux-controlled memristor emulator which originally reported in [3] based on a third-
