  • Patent number: 7844798
    Abstract: A method of operating an integrated circuit involves supplying an instruction portion of a command to the integrated circuit to specify an operation to be performed by the integrated circuit. At least some types of commands also include an attributes portion that provides additional information about the operation to be performed. The attributes portion of the command is supplied to the integrated circuit with a delay relative to the instruction portion of the command. The integrated circuit selectively enables circuitry for processing the attributes portion if the integrated circuit determines from the received instruction portion that the command also includes an attributes portion. The delay between the two portions of the command provides sufficient time for the integrated circuit to enable the attributes processing circuitry, which, in a default state, can be disabled during an active mode of the integrated circuit to save power.

  • Publication number: 20090267678
    Abstract: An integrated circuit includes: a terminal for outputting data, a driver for providing the data to the terminal, and a switch for selectively connecting/disconnecting the driver to the terminal. The disconnection of the driver reduces the capacitive load on the connection between the terminal and driver, thus reducing limitations on data rate from factors such as data reflections that reduce signal quality. Selective connection/disconnection allows the driver to be reconnected to the terminal only when needed.
