STMicroelectronics Assigned Two Patents

NVM with asymmetric row decoder and method for selecting word lines
STMicroelectronics S.r.l., Agrate Brianza, Italy, has been assigned a patent (11,380,380) developed by Disegni, Fabio Enrico Carlo, Spino d’adda, Italy, Perroni, Maurizio Francesco, Messina, Italy, Torti, Cesare, Pavia, Italy, and Scardino, Guiseppe, Poggioreale, Italy, for “non volatile memory device with an asymmetric row decoder and method for selecting word lines.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A non-volatile memory device including an array of memory cells coupled to word lines and a row decoder, which includes a first and a second pull-down stage, which are arranged on opposite sides of the array, and include, respectively, for each word line, a corresponding first pull-down switching circuit and a corresponding second pull-down switching circuit, which are coupled to a first point and a second point, respectively, of the first word line. The row decoder moreover comprises a pull-up stage, which includes, for each word line, a corresponding pull-up switching circuit, which can be electronically controlled in order to: couple the first point to a supply node in the step of deselection of the word line, and decouple the first point from the supply node in the step of selection of the word line.”

The patent application was filed on November 3, 2020 (17/088,060).

Writing data in memory of contactless transponder, and corresponding contactless transponder
STMicroelectronics (Rousset) SAS, Rousset, France, has been assigned a patent (11,380,377) developed by Tailliet, Francois, Fuveau, France, Brochier, Beatrice, Chateauneuf, France, and Fidelis, Sylvain, Belcodene, France, for “method for writing data in a memory of a contactless transponder, and corresponding contactless transponder device.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A contactless transponder includes a non-volatile static random access memory including memory points. Each memory point is formed by a volatile memory cell and a non-volatile memory cell. A protocol processing circuit receives data and stores the received data in the volatile memory cells of the memory. A write processing circuit is configured, at the end of the reception and storage of the data, to record, in a single write cycle, the data from the volatile memory cells to the non-volatile memory cells of the respective memory points.”

The patent application was filed on March 1, 2021 (17/188,569).
