摘要： Apparatus and methods of reducing power consumption in solid-state storage devices such as solid-state disks (SSDs) that can reduce idle power levels in an SSD, while maintaining low resume latency upon exiting a reduced power state. By arranging a storage controller and at least one NAND flash package of the SSD in separate power islands, storing context information for the SSD in at least one page buffer of NAND flash memory within the NAND flash package on one power island upon entering the reduced power state, and, once the context information is stored in the page buffer, allowing the NAND flash memory to enter a standby mode, placing the storage controller on the other power island in a predefined low power mode, and removing power from any unneeded components on the same power island as the storage controller, a scalable approach to reducing idle power levels in the SSD can be achieved.

摘要： A method and apparatus for reducing the disk drive data transfer interrupt service latency penalty is described. The method comprises beginning a data transfer between a disk drive and a host system, issuing an interrupt before the transfer is complete, and then completing the data transfer. This method may be implemented on a computer assembly that includes a processor, an input/output controller, and a scatter/gather list, which is stored in memory, that includes an entry that will cause the input/output controller to generate the interrupt.

摘要： Embodiments include apparatuses, method, and systems for managing a transfer buffer associated with a non-volatile memory. In one embodiment, controller logic may be coupled to a non-volatile memory and a transfer buffer. The controller logic may read a plurality of sectors of data from the non-volatile memory and store the read sectors in the transfer buffer. The controller logic may further allocate individual sectors to pages according to a completion time of the read of individual sectors of the plurality of sectors, the individual pages including a plurality of the sectors. The controller logic may further write the pages of sectors to the non-volatile memory responsive to a determination that all sectors of the page have been read.

摘要： An apparatus is equipped with a caching function of a device driver, including a pre-fetch function that selective pre-fetches data stored in disk blocks to facilitate operation with a file system having file clusters with a cluster size greater than an underlying operating system's memory page size. The apparatus is further equipped with a disk block allocation optimization function to generate a new set of disk blocks to reallocate disk blocks for file system clusters accessed by a sequence of file accesses of interest to improve the overall access time for these file system clusters. The disk block allocation optimization function is further equipped to account for the selective pre-fetches and caching to be performed to accommodate said file system.

摘要： An optimized CD/DVD authoring method is disclosed. Either a pre-final version of a CD/DVD having a first block allocation or a disk image of the pre-final version of the CD/DVD with the first block allocation is first created. An alternate block allocation to the first block allocation that yields improved overall access time for the content of the CD/DVD is generated, if possible, based on the order a selected subset or the entire content of the CD/DVD is accessed. A final version of the CD/DVD is then generated using the alternate block allocation.
