  • Patent number: 10216637
    Abstract: In order to provide a more efficient persistent storage device, one or more long-term storage media are included along with a non-volatile memory. In one embodiment, one portion of the non-volatile memory is used as a write buffer and a read cache for writes and reads to the long-term storage media. Interfaces are provided for controlling the use of the non-volatile memory as a write buffer and a read cache. Additionally, a portion of the non-volatile memory is used to provide a direct mapping for specified sectors of the long-term storage media. Descriptive data regarding the persistent storage device is stored in another portion of the non-volatile memory.

  • Patent number: 9996392
    Abstract: In embodiments of an idle time service, it can be determined that processing on a device is in an idle state. An execution duration of applications that are scheduled to be executed by a processor of the device can then be extended to reduce power consumption by the device. In other embodiments, it can be determined that an application configured to execute on a device is a background application. The execution duration of the background application can then be extended to reduce power consumption by the device.

  • Patent number: 7082495
    Abstract: A method and apparatus to improve the read/write performance of a hard drive is presented. The hard drive includes solid state, non-volatile (NV) memory as a read/write cache. Data specified by the operating system is stored in the NV memory. The operating system provides a list of data to be put in NV memory. The data includes data to be pinned in NV memory and data that is dynamic. Pinned data persists in NV memory until the operating system commands it to be flushed. Dynamic data can be flushed by the hard drive controller. Data sent by an application for storage is temporary stored in NV memory in data blocks until the operating system commits it to the disk.
