Novel crossbar array of silicon nitride resistive memories on SOI enables memristor rationed logic

Abstract

In this work, the fabrication of crossbar arrays of silicon nitride resistive memories on silicon-on-insulator substrate and their utilization to realize multi-rationed logic circuits are presented. Typical electrical characterization of the memristors revealed their ability of multi-state operation by the presence of 12 well separated resistance levels. Through a dedicated modeling and fitting procedure of these levels, a reconfigurable logic based on memristor rationed logic scheme is designed and a crossbar integration methodology was proposed. Finally, several circuitry aspects were simulated in SPICE with a silicon nitride SOI crossbar array calibrated model and power optimization prospects were discussed.
