  • Patent number: 8745427
    Abstract: Embodiments of the invention describe systems and processes directed towards improving link power-management during memory subsystem idle states. Embodiments of the invention control memory link operations when various components of a memory subsystem enter low power states under certain operating conditions. Embodiments of the invention similarly describe exiting low power states for memory links and various components of a memory subsystem upon detecting certain operating conditions. Embodiments of the invention may detect operating conditions in a computing system. Some of these operating conditions may include, but are not limited to, a memory controller being empty of transactions directed towards a memory unit, a processor core executing a processor low-power mode, and a processor socket executing an idle mode. In response to detecting said operating conditions, embodiments of the invention may execute a low-power idle state for the memory unit and various components of the memory subsystem.

  • Patent number: 8683189
    Abstract: A boot method an apparatus are described which reduce the likelihood of a security breach in a mobile device, preferably in a situation where a reset has been initiated. A predetermined security value, or password, is stored, for example in BootROM. A value of a security location within FLASH memory is read and the two values are compared. Polling of the serial port is selectively performed, depending on the result of such comparison. In a presently preferred embodiment, if the value in the security location matches the predetermined security value, then polling of the serial port is not performed. This reduces potential security breaches caused in conventional arrangements where code may be downloaded from the serial port and executed, which allows anyone to access and upload programs and data in the FLASH memory, including confidential and proprietary information.

  • Patent number: 8683253
    Abstract: An apparatus that compensates for misalignment on a synchronous data bus, including a resistor network, a transmitting device, and a receiving device. The resistor network indicates an amount to advance a synchronous data strobe associated with a data group. The transmitting device has a core clocks generator and a synchronous strobe driver. The core clocks generator advances a data strobe clock by the amount. The synchronous strobe driver employs the data strobe clock to generate the synchronous data strobe, where the synchronous data strobe is advanced also by the amount. The receiving device has a composite delay element and delay-locked loops (DLLs). The composite delay element equalizes delay paths within the receiving device, where the delay paths correspond to the synchronous data strobe that is received from the transmitting device.

  • Patent number: 8677111
    Abstract: Virtual storage arrays consolidate data storage at a data center for physical and virtual computer systems at one or more branch network locations. Standalone and virtualized computer systems at a branch network location load, execute, and store their operating systems, applications, and data using virtual storage arrays and do not require any built-in or external non-volatile data storage devices such as hard disk drives or solid-state drives at the branch network location. The virtual disks of the virtual storage array are mapped to physical data storage at the data center and accessed via a WAN using storage block-based protocols. A storage block cache at the branch network location includes storage blocks prefetched based on knowledge about the computer systems at the branch network location and the behavior of their operating systems and applications.
