Patent number: 10074522Abstract: The present invention relates to systems and methods for preparing reactively sputtered films. The films are generally thin transition metal oxide (TMO) films having an optimum stoichiometry for any useful device (e.g., a sub-stoichiometric thin film for a memristor device). Described herein are systems, methods, and calibrations processes that employ rapid control of partial pressures to obtain the desired film.Type: GrantFiled: March 27, 2015Date of Patent: September 11, 2018Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: James E. Stevens, Patrick R. Mickel, Andrew Lohn, Matthew Marinella

Patent number: 9412446Abstract: The present invention relates to resistive random-access memory (RRAM or ReRAM) systems, as well as methods of employing multiple state variables to form degenerate states in such memory systems. The methods herein allow for precise write and read steps to form multiple state variables, and these steps can be performed electrically. Such an approach allows for multilevel, high density memory systems with enhanced information storage capacity and simplified information retrieval.Type: GrantFiled: August 18, 2014Date of Patent: August 9, 2016Assignee: Sandia CorporationInventors: Andrew Lohn, Patrick R. Mickel

Patent number: 9336870Abstract: The present invention is directed generally to resistive random-access memory (RRAM or ReRAM) devices and systems, as well as methods of employing a thermal resistive model to understand and determine switching of such devices. In particular example, the method includes generating a power-resistance measurement for the memristor device and applying an isothermal model to the power-resistance measurement in order to determine one or more parameters of the device (e.g., filament state).Type: GrantFiled: February 3, 2015Date of Patent: May 10, 2016Assignee: Sandia CorporationInventors: Patrick R.
