    Abstract: A programmable semiconductor integrated circuit fabricated on a single microchip device capable of being selectively programmed to perform one or more logic functions provides a sleep mode using an intermittent power saving logic. The circuit includes configurable logic blocks (“LB”), memory, switch, and sleep controller. While LB can enter a power saving sleep mode (“PSSM”) in accordance with its power supply, the memory stores the configuration information for the LB. The switch is configured to manage the LB power supply based on a configurable sleep signal for facilitating the PSSM. The sleep controller facilitates generation of the configurable sleep signal in response to the signal from a power saving output port associated with the LB.

    Abstract: Embodiments of recovering data in computing devices and associated methods of operations are disclosed therein. In one embodiment, a method includes receiving a failure notification indicating that a core of a main processor is experiencing a catastrophic failure causing the core unable to execute instructions. In response, a flush command can be issued to an uncore of the processor via a debug port instructing the uncore to copy any data currently residing in a processor cache of the main processor to a volatile memory. The method further includes issuing a self-refresh command causing the volatile memory to enter a self-refresh mode in which the data copied from the processor cache is maintained and unmodifiable by the main processor during a reset of the main processor.

  • Patent number: 10001947
    Abstract: An example computer-implemented method for performing efficient patrol read operations in a storage system including a plurality of disks organized in a RAID array can include determining an I/O load on the storage system, identifying at least one portion of an available storage capacity containing valid data and reading the portion of the available storage capacity containing the valid data. Optionally, the portion of the available storage capacity containing the valid data is the only portion read during the patrol read operations. The method can also include determining whether a medium error exists in the portion of the available storage capacity containing the valid data. If a medium error exists, the method can include fixing the medium error. Additionally, the above operations can optionally be performed only when the I/O load on the storage system is less than a predetermined threshold.

  • Patent number: 9904818
    Abstract: Provided are RFID systems, methods and RFID tags according to various aspects. An infrared (IR) beam, from an IR transmitter, is outputted in a first direction so that an RFID tag with an IR sensor adds a flag to stored data in the RFID tag in response to the RFID tag's IR sensor detecting the IR beam. An RF interrogation signal is outputted by an RFID reader, and a response is received from the RFID tag to the RF interrogation signal. It is determined whether the flag is contained in the RFID tag's response to the RF interrogation signal, and if so, the RFID tag is determined to be in the first direction relative to the IR transmitter.

  • Patent number: 9880783
    Abstract: Systems and methods for managing transfer of data into and out of a host data buffer of a host are disclosed. In one implementation, a partial write completion module of a storage system retrieves from the host, stores in a memory, and acknowledges retrieving and storing with a partial write completion message, each subset of a larger set of data associated with a host write command. The host may utilize received partial write completion messages to release and use the portion of the host data buffer that had been storing the subset identified in the message rather than waiting to release data associated with the host write command until all the data associated with the command is stored in the memory. The memory in which each subset is stored may be non-volatile memory in the storage device or a shadow buffer on the host or an external memory device.

  • Patent number: 9883067
    Abstract: A control apparatus includes a first control unit, a second control unit including a memory for storing information for performing startup processing, and a power supply unit configured to supply electric power to the first control unit and the second control unit, and in a case where electric power is supplied from the power supply unit to the second control unit, whether a startup state of the second control unit is normal is determined. In a case where the startup state of the second control unit is determined to be normal, the power supply unit supplies electric power to the first control unit. In a case where the startup state of the second control unit is determined to be not normal, to power supply to the memory from a backup power supply for the memory is stopped so as to clear the memory of the second control unit.

  • Patent number: 9870281
    Abstract: A Data Storage Device (DSD) includes a disk for storing data, a volatile memory for temporarily storing data to be written on the disk, and a Non-Volatile Solid-State Memory (NVSM) for storing data. Data is stored in the volatile memory in preparation for writing the data on the disk. The data is written from the volatile memory onto the disk, and it is determined whether the data written on the disk is qualified as written. In the event of an unexpected power loss, a portion of unqualified data that has not been qualified as written is transferred from the volatile memory to the NVSM.

  • Patent number: 9811456
    Abstract: In one form, a data processor comprises a memory accessing agent and a memory controller. The memory accessing agent selectively initiates read accesses to and write accesses from a memory. The memory controller is coupled to the memory accessing agent and is adapted to be coupled to the memory and to access the memory using a start-gap wear-leveling algorithm. The memory controller is adapted to maintain a metadata log in a region of the memory and to store in the metadata log a start address and a gap address used in the start-gap wear-leveling algorithm, and upon initialization to access the metadata log to retrieve an initial start address and an initial gap address for use in the start-gap wear-leveling algorithm. In another form, a memory module may comprise a memory buffer including such a memory controller.

  • Patent number: 9753828
    Abstract: Maintaining failure survivability in a storage system includes determining a save time corresponding to an amount of time needed to transfer system data from volatile memory to non-volatile memory, determining a threshold corresponding to time for batteries to run while transferring data from volatile memory to non-volatile memory after a power loss, and providing an indication in response to the save time being greater than the threshold. The system may include a plurality of directors and the save time and the threshold may be determined for each of the directors. Determining a threshold may include determining an amount of battery time provided by battery power following power loss and multiplying the amount of battery time by a factor less than one, such as 0.8.

  • Patent number: RE47621
    Abstract: A high security microcontroller (such as in a point of sale terminal) includes tamper control circuitry for detecting vulnerability conditions: a write to program memory before the sensitive financial information has been erased, a tamper detect condition, the enabling of a debugger, a power-up condition, an illegal temperature condition, an illegal supply voltage condition, an oscillator fail condition, and a battery removal condition. If the tamper control circuitry detects a vulnerability condition, then the memory where the sensitive financial information could be stored is erased before boot loader operation or debugger operation can be enabled. Upon power-up if a valid image is detected in program memory, then the boot loader is not executed and secure memory is not erased but rather the image is executed. The tamper control circuitry is a hardware state machine that is outside control of user-loaded software and is outside control of the debugger.
