Patents by Inventor Frederic Cherpantier

Frederic Cherpantier has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8370644
    Abstract: Systems and methods that facilitate securing data associated with a memory from security breaches are presented. A memory component includes nonvolatile memory, and a secure memory component (e.g., volatile memory) used to store information such as secret information related to secret processes or functions (e.g., cryptographic functions). A security component detects security-related events, such as security breaches or completion of security processes or functions, associated with the memory component and in response to a security-related event, the security component can transmit a reset signal to the secure memory component to facilitate efficiently erasing or resetting desired storage locations in the secure memory component in parallel and in a single clock cycle to facilitate data security. A random number generator component can facilitate generating random numbers after a reset based on a change in scrambler keys used by a scrambler component to descramble data read from the reset storage locations.

  • Publication number: 20090106577
    Abstract: Systems and/or methods that facilitate expediently transmitting and programming data to an electronic device that contains nonvolatile memory are presented. A host component facilitates the determination of different clock frequencies that an electronic device(s) can accommodate for transmitting data to and receiving data from the electronic device. The host component can facilitate transmitting data to the electronic device at a higher clock frequency than the clock frequency utilized to transmit data from the electronic device to the host component in order to facilitate programming large amounts of data to the electronic device efficiently. The host component can select a downlink and/or uplink clock frequency based in part on the type of electronic device(s), the size of a memory buffer associated with the nonvolatile memory device, and/or a type of protocol associated with the electronic device.
