IP GEM Group, LLC, Irvine, CA, has been assigned a patent (9,799,405) developed by Micheloni, Rino, Turate, Italy, Marelli, Alessia, Dalmine, Italy, and Bates, Stephen, Canmore, CA, for a "nonvolatile memory system with read circuit for performing reads using threshold voltage shift read instruction."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A nonvolatile memory system, a nonvolatile memory controller and a method for reducing latency of a memory controller are disclosed. The nonvolatile memory controller includes a storage module configured to store data indicating threshold voltage shift read parameters and corresponding index values. The nonvolatile memory controller includes a status circuit configured to determine at least one usage characteristic of a nonvolatile memory device, and a read circuit configured to determine whether a usage characteristic meets a usage characteristic threshold. When a usage characteristic is determined to meet the usage characteristic threshold, the read circuit is configured to perform all subsequent reads of the nonvolatile memory device using a threshold voltage shift read instruction identified using one or more of the threshold voltage shift read parameters.

The patent application was filed on July 29, 2015 (14/812,891).
