STMicroelectronics Assigned Patent

STMicroelectronics S.r.l., Agrate Brianza, Italy , has been assigned a patent (11645004) developed by Disegni, Fabio Enrico Carlo, Spino d’adda, Italy, for a “real-time update method for a differential memory, differential memory and electronic system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for operating a differential memory includes: operating a main memory module differentially while executing a first program, copying first logic data from a first submodule of the main memory module to an auxiliary memory module, storing third logic data associated with a second program in a second submodule of the main memory module by overwriting second logic data associated with the first program, while maintaining the first logic data contained in the first submodule of the main memory module unaltered, where the second logic data are complementary to the first logic data, when a request for reading the first logic data is received during the storing of the third logic data in the second submodule of the main memory module, reading the first logic data from the auxiliary memory module, and executing the first or second programs by operating the main memory module in single-ended mode.”

The patent application was filed on 2022-02-08 (17/667087).
