Patent number: 9639131Abstract: A variety of data storage devices, methods and systems are implemented for control of memory associated with backup functionality. One such data storage device includes a power circuit that provides main power. The data storage device has a first solid-state memory circuit that maintains data in the absence of electrical power. A second memory circuit is subject to data loss in the absence of electrical power. A storage circuit stores energy and provides the stored energy to the second memory circuit in response to a loss of main power. A test circuit discharges a portion of the stored energy to provide output data indicative of power-providing capabilities of the storage circuit. A memory controller controls data transfers to the data storage device by temporarily storing data destined for the first solid-state memory circuit and setting the amount of memory available for temporary storage in response to the output data.Type: GrantFiled: May 9, 2014Date of Patent: May 2, 2017Assignee: Seagate Technology LLCInventors: Michael Howard Miller, Martin Ragnar Furuhjelm, Jonathan Williams Haines

Patent number: 8832409Abstract: A fixed data region on a storage medium may be allocated with one of a variety of allocation schemes (e.g., a randomly writable allocation scheme, a non-randomly writeable allocation scheme with a first data isolator spacing, a non-randomly writeable allocation scheme with a second data isolator spacing, and a non-randomly writeable allocation scheme with no dynamic isolators). Dynamic sub-region spacing refers at least to the number of data tracks in a data region of a magnetic disc between dynamic isolators and the number of bits in a data region in flash memory between dynamic isolators. The presently disclosed technology adapts isolators on the storage medium to create dynamic sub-regions based on characteristics of the storage medium, characteristics of the data, and/or expected access patterns of data to be written to the storage medium.Type: GrantFiled: March 9, 2011Date of Patent: September 9, 2014Assignee: Seagate Technology LLCInventors: Timothy Richard Feldman, Jonathan Williams Haines
