Robert Edwin Payne 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: 7681057
    Abstract: Methods and apparatus for placing a non-volatile memory systems in one of a number of power-down modes in response to events being monitored are useful in reducing power consumption of the non-volatile memory system. The power-down modes provide for successively less functionality, thus providing for successively less power consumption. A non-volatile memory system thus can respond to the events to place the system in a mode that permits the desired operation or a desired response time for subsequent operations while seeking to minimize power consumption.
    Type: Grant

  • Patent number: 7254724
    Abstract: According to one embodiment of the present invention, there is provided a power management system for use in a computer system having a memory system incorporating a non-volatile memory and a controller which presents the logical characteristics of a disc storage device to a host, the power management system comprising means for monitoring the operational activity levels within at least some of the components of the controller and arranged, in response to the monitored levels, to vary the power consumed by selected components of the controller.

  • Patent number: 7000064
    Abstract: In one embodiment of the present invention, there is disclosed, a method of handling data which is being written to and stored in flash memory, wherein input data, comprising information data and overhead data, undergoes a reversible transformation before being written to flash memory whereupon each bit stored in flash memory, as flash data, is a function of both information data and header data.

  • Patent number: 6711059
    Abstract: According to a first aspect of the present invention, there is provided a memory system having a controller and a non-volatile memory storing firmware for start up and for normal operation of the system, the controller comprising, a volatile memory; and a processor; wherein the controller is arranged to operate during initialization or configuration of the system so that the start up firmware stored in the non-volatile memory is loaded into the volatile memory under hardware control by the controller and with the processor halted, the start up firmware in the volatile memory being subsequently executed by the processor.
