20060117156 - Method and apparatus for dual protection of a protected memory block: If the logic module detects the hardware state as a write permit state (118) and the logic module fails to receive the write-protect signal (116), the logic module permits the memory controller to modify the protected memory block. If the logic module either detects the hardware state is a write...

20060117155 - Micro-threaded memory: A micro-threaded memory device. A plurality of storage banks are provided, each including a plurality of rows of storage cells and having an access restriction in that at least a minimum access time interval must transpire between successive accesses to a given row of the storage cells. Transfer control circuitry...

20060117158 - Method for managing viewing of a particular content recorded on an information recording medium: A DVD player 11 reads disc control information recorded on a DVD medium M and causes a display 12 to display a start menu screen, thereby prompting a viewer to perform authentication (1). The viewer uses a remote controller 11a to display a first viewer authentication screen (2). Then, an...

20060117159 - Data storage system and data storage control device: A storage system has a plurality of control modules for controlling a plurality of storage devices, which make mounting easier with maintaining low latency response even if the number of control modules increases. A plurality of storage devices are connected to the second interface of each control module using back...

20060117160 - Method to consolidate memory usage to reduce power consumption: A method and system for reducing power consumption of a computer system by allocating memory pages that are associated with lower memory address before those associated with higher memory addresses. Memory elements that do not include any allocated memory pages and that are positioned at a higher address than a...

20060117161 - Method and apparatus for configuring a storage device: A method and apparatus is disclosed in which a storage device controller is arranged to use a set of sequential physical block addresses on a storage device as a single logical block address....

20060117162 - System and method for information handling system memory page mapping optimization: Plural consecutive virtual memory pages associated with an application running on an information handling system are mapped to a physical memory page of the information handling system's physical memory, such as dual channel interleaved memory. Each physical memory page that stores plural consecutive virtual memory pages becomes an effective cache...
