STMicroelectronics Assigned Two Patents

Secure non-volatile memory
STMicroelectronics (Alps) SAS, Grenoble, France, has been assigned a patent (12008244) developed by Benhammadi; Jawad, Pont de Claix, France, for a “secure non-volatile memory.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The present description concerns a method comprising: the loading, from a non-volatile memory of a circuit to a computation circuit, of a first security parameter of the circuit and of a first error-correcting code stored in association with the first security parameter; the verification, by the computation circuit, of the first security parameter and of the first error-correcting code to determine whether one or a plurality of the bits of the security parameter are erroneous; and if it is determined that two bits of the security parameter are erroneous, the loading of a default value of the first parameter into a register.”

The patent application was filed on 2022-06-30 (17/810093).

Phase-change memory
STMicroelectronics (Crolles 2) SAS, Crolles, France, and STMicroelectronics (Rousset), Rousset, France, has been assigned a patent (12004432) developed by Boivin; Philippe, Venelles, France, Simola; Roberto, Trets, France, and Moustapha-Rabault; Yohann, Saint-Egreve, France, for a “phase-change memory.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The present description concerns a device including phase-change memory cells, each memory cell including a first resistive element in lateral contact with a second element made of a phase-change material.”

The patent application was filed on 2021-10-21 (17/507645).
