Silicon Laboratories Assigned Patent

Silicon Laboratories Inc., Austin, TX, has been assigned a patent (12175118) developed by David; Thomas Saroshan, Lakeway, TX, Rafi; Aslam, Norem; Joshua, Austin, TX, Bink; Adrianus Josephus, Oslo, Norway, and Cooley; Daniel, Austin, TX, for an “external nonvolatile memory with additional functionality.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “An external nonvolatile memory device that includes a rewritable nonvolatile memory and a CMOS interface is disclosed. The interface includes a clock signal which is input to the external nonvolatile memory device. This clock signal is multiplied by an integer to create a memory serdes clock which is used to clock outgoing data. The memory serdes clock is also used to create a clock that is used to clock the incoming data from the main processing device. The external nonvolatile memory device also includes an encryption/decryption block that encrypts data read from the nonvolatile memory before it is transmitted over the interface, and decrypts data received from the interface before storing it in the nonvolatile memory. The encryption/decryption block may utilize a stream cipher.”

The patent application was filed on 2022-03-22 (17/700906).
