Abstract

The unique adaptive properties of memory resistors (memristors) are ideal for use in computational architectures. Multiple interconnected memristors demonstrate complicated overall behavior which significantly improves the efficiency of logic operations via massive parallelism. Nowadays, within an ever-growing variety of memristive systems, most of the research has so far focused on the properties of the individual devices; little is known about the extraordinary features of complex memristive networks and their application prospects. The composite characteristics of regular and irregular memristive networks are explored in this work. A generalized concept for the construction of composite memristive systems, efficiently built out of individual memristive devices, is presented. A new type of threshold-dependent programmable memristive switches. presenting different electrical characteristics from their structural elements, is proposed. As an example of the introduced approach, a SPICE simulation-based evaluation of several programmable analog circuits is presented. The proposed circuit design approach constitutes a step forward towards novel memristor-based nanoelectronic computational systems and architectures. (C) 2014 Elsevier Ltd. All rights reserved.
