Abstract

This work presents the co-integration of resistive random access memory crossbars within a 180nm Read-Write CMOS chip. TaOx-based ReRAMs have been fabricated and characterized with materials and process steps compatible with the CMOS Back-End-of-the-Line. Two different strategies, consisting in insertion of an Al2O3tunnel barrier layer and the design of a dedicated CMOS read circuit, have been developed in order to increase the cell high-to-low resistance ratio of a factor of 1000 and to reduce the sneak-path current effects by one order of magnitude. The ReRAM cells have been integrated directly on a standard CMOS foundry chip, enabling low cost ReRAM-CMOS integration. The integrated memories show a set and reset voltages of -1 and 1.3V, respectively. The measured operating voltages are compatible for low-voltage applications.

Integrated circuit

An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or "chip") of semiconductor material, usually silicon. Large numbers of miniaturized transistors and other electronic components are integrated together on the chip. This results in circuits that are orders of magnitude smaller, faster, and less expensive than those constructed of discrete components, allowing a large transistor count.

Mixed-signal integrated circuit

A mixed-signal integrated circuit is any integrated circuit that has both analog circuits and digital circuits on a single semiconductor die. Their usage has grown dramatically with the increased use of cell phones, telecommunications, portable electronics, and automobiles with electronics and digital sensors. Integrated circuits (ICs) are generally classified as digital (e.g. a microprocessor) or analog (e.g. an operational amplifier). Mixed-signal ICs contain both digital and analog circuitry on the same chip, and sometimes embedded software.

GlobalFoundries

GlobalFoundries Inc. (GF) is a multinational semiconductor contract manufacturing and design company incorporated in the Cayman Islands and headquartered in Malta, New York. Created by the divestiture of the manufacturing arm of AMD, the company was privately owned by Mubadala Investment Company, the sovereign wealth fund of the United Arab Emirates, until an initial public offering (IPO) in October 2021. The company manufactures integrated circuits on wafers designed for markets such as mobility, automotive, computing and wired connectivity, consumer internet of things (IoT) and other industrial applications.
