Sandia Assigned Patent
Multilevel resistive information storage and retrieval
By Francis Pelletier | August 30, 2016 at 2:59 pmSandia Corporation, Albuquerque, NM, has been assigned a patent (9,412,446) developed by Lohn, Andrew, and Mickel, Patrick R., Albuquerque, NM, for a “multilevel resistive information storage and retrieval.“
The abstract of the patent published by the U.S. Patent and Trademark Office states: “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.“
The patent application was filed on August 18, 2014 (14/462,472).
