    Abstract: An apparatus includes a controller capable of being coupled to a host interface and a memory device. The memory device includes two or more non-hierarchical, non-volatile memory units having different minimum addressable data unit sizes. The controller is configured to at least perform determining a workload indicator of a data object being stored in the memory device via the host interface. The controller selects one of the memory units in response to the workload indicator of the data object corresponding to the minimum addressable data unit size of the selected memory unit corresponding to the workload indicator. The data object is stored in the selected memory unit in response thereto.

    Abstract: Quality of service indicators are provided from a host via a host interface. The quality of service indicators relate to data stored in a non-volatile data storage via the host. Workload indicators related to the quality of service indicators are measured, and a weighting is assigned to the host in response to a correlation between the quality of service indicators and the measured workload indicators. The weighting is applied to the quality of service indicators when responding to data access requests from the host.

    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: Method and apparatus for managing data in a memory. In accordance with some embodiments, a recovery data set representing a current state of a storage device is stored in a rewritable non-volatile memory responsive to detection of a potentially imminent deactivation of the device. The recovery data set is swapped with a boot data set in said memory responsive to subsequent deactivation of the device. The boot data set is subsequently used to transition the device from a deactivated mode to an operationally ready mode during device reinitialization. The boot data set is thereafter swapped with the recovery data set to return the device to the current state.

    Abstract: Method and apparatus for managing data in a memory. In accordance with some embodiments, a first tier of a multi-tier memory structure is arranged into a plurality of garbage collection units (GCUs). Each GCU is formed from a plurality of non-volatile memory cells, and is managed as a unit. A plurality of data sets is stored in a selected GCU. A garbage collection operation is performed upon the selected GCU by identifying at least one of the plurality of data sets as a valid data set, migrating the valid data set to a non-volatile second tier of the multi-tier memory structure, and invalidating a programmed state of each of the plurality of non-volatile memory cells to prepare the selected GCU for storage of new data. In some embodiments, the invalidating operation involves setting all of the memory cells in the selected GCU to a known storage state.

    Abstract: Method and apparatus for managing data in a memory. In accordance with some embodiments, input write data having a selected logical address are stored in a rewriteable non-volatile (NV) buffer. A copy of the input write data is transferred to an NV main memory using a sloppy write process. A verify operation is subsequently performed to verify successful transfer of the copy of the input write data to the NV main memory using a hash value generated responsive to the input write data in the NV buffer.
