Abstract: 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.

Abstract: Systems and methods presented herein provide a controller is operable to increase a number of suspend operations during read Input/Output (I/O) operations of a storage device, and to detect an increase in response times for write commands due to the increased number of suspend operations. The controller is also operable to decrease the number of the suspend operations during the reads of the storage device to decrease the response times of the write commands.

Abstract: A storage compute device includes a data storage section that facilitates persistently storing host data as data objects. The storage compute device also includes two or more compute sections that perform computations on the data objects. A controller monitors resource collisions affecting a first of the compute sections. The controller creates a copy of at least one of the data objects to be processed in parallel at a second of the compute sections in response to the resource collisions

Abstract: Systems and methods presented herein provide a controller that is operable to monitor a plurality of background commands to a storage device over a pre-determined period of time and to determine how often each of the background commands is issued during the pre-determined period of time. The controller is further operable to establish a time interval for each of the background commands, and to issue each of the background commands at their respective time intervals.

Abstract: The disclosed technology provides for a solid state device that adaptively determines, responsive to receipt of a write command, whether or not to partition one or more individual logical blocks of data between multiple pages of a flash storage device. According to one implementation, the partitioning (e.g., spanning) determination is based on read frequency characteristics and the internal error correction code rate of the data.

Abstract: Computations are performed on data objects via two or more data storage sections. The data storage sections facilitate persistently storing the data objects in parallel read/write operations. The data objects are used in computations within a storage compute device. At least one of the storage sections is deactivated during the computations to reduce power usage of the storage compute device.

Abstract: Methods and apparatuses facilitate receiving a command via a host interface of a storage compute device to perform a computation on one or more data objects. The computations producing intermediate objects that are stored in data storage section of the storage compute device. A determination is made to compress and decompress the intermediate objects as they are moved between the data storage section and a compute section based on wear of a storage medium being reduced in response to the compression and decompression. The intermediate objects are compressed and decompressed as they are moved between the data storage section and the compute section in response to the determination.

Abstract: An incremental signal is defined that includes at least one of a duration and a peak voltage that is less than a respective minimum programming time or minimum programming voltage step of a resistive memory element. A characterization procedure is repeatedly performed that at least involves: applying a signal to the memory element, the signal being incremented by the incremental signal during each subsequent application; measuring a first resistance of the memory element in response to the signal; and c) measuring a second resistance of the memory element after a time period has elapsed from the measurement of the first resistance with no programming signal applied. In response to the first and second resistance measurements of the characterization procedure, a characterization parameter of the memory element is formed.

Abstract: 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. The upper and lower memory tiers each are formed of rewritable memory cells having different constructions and storage attributes.
