Patent number: 11687292Abstract: Method and apparatus for managing data in a cloud computing environment. In accordance with some embodiments, data updates are received to a multi-tier memory structure across a cloud network and stored as working data in an upper rewritable non-volatile memory tier of the memory structure. The working data are periodically logged to a lower non-volatile memory tier in the memory structure while a current version of the working data remain in the upper memory tier.

Patent number: 10997068Abstract: Methods, apparatuses, and computer-readable media for providing extremely rapid preconditioning of an SSD. Upon receiving a precondition command from a host operably connected to the SSD to precondition a range of LBAs of the storage media, a plurality of physical units of the storage media to be preconditioned are determined based on the range of LBAs. A workload pattern is determined from the precondition command, and upon determining that the workload pattern indicates a random pattern, a valid page count for each of the plurality of physical units is computed based on a random distribution. Forward mapping table entries of a forward mapping table associated with the storage media corresponding to the range of LBAs is then populated with random physical addresses from the plurality of physical units based at least on the computed valid page count for each of the plurality of physical units.Type: GrantFiled: February 12, 2020Date of Patent: May 4, 2021Assignee: Seagate Technology LLCInventors: David Scott Ebsen, Dana Lynn Simonson

Patent number: 10739996Abstract: Systems and methods are disclosed for enhanced garbage collection operations at a memory device. The enhanced garbage collection may include selecting data and blocks to garbage collect to improve device performance. Data may be copied and reorganized according to a data stream via which the data was received, or data and blocks may be evaluated for garbage collection based on other access efficiency metrics. Data may be selected for collection based on sequentiality of the data, host access patterns, or other factors. Processing of host commands may be throttled based on a determined amount of work to garbage collect a plurality of blocks, in order to limit variability in host command throughput over a time period.Type: GrantFiled: July 18, 2016Date of Patent: August 11, 2020Assignee: Seagate Technology LLCInventors: David Scott Ebsen, Kevin A Gomez, Mark Ish, Daniel John Benjamin, Robert Wayne Moss

Patent number: 10509747Abstract: A memory controller manages memory access operations through a flash memory interface of a memory array of a solid-state storage device connected to a host. The memory controller executes a first memory access operation in the memory array. The first memory access operation has a first priority. The memory controller detects a suspending memory access operation available for execution in the memory array and having a higher priority than the first priority. The detection operation distinguishes between suspending memory access operations and non-suspending memory access operations. The memory controller suspends execution of the first memory access operation in the memory array and executes one or more memory access operations having higher priorities than the first priority and being available for execution in the memory array. The memory controller resumes the execution of the first memory access operation in the memory array.Type: GrantFiled: May 17, 2018Date of Patent: December 17, 2019Assignee: SEAGATE TECHNOLOGY LLCInventors: David Scott Ebsen, Dana Lynn Simonson, AbdelHakim Alhussien, Erich Franz Haratsch, Steven Howe
