    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: Parameters indicative of resistance variance of the memory elements are tracked. The resistance variance affects values of data stored in the resistance-based memory elements. A hash function is performed for each memory element. The hash function returns a reference to one of a plurality of counter elements. A value of each counter element is modified in response to the tracked parameter data of the associated memory element. Read operations affecting the memory elements are adjusted based on the values for the associated counter elements.

    Abstract: A data storage device includes one or more storage media that include multiple physical storage locations. The device also includes at least one cache memory having a logical space that includes a plurality of separately managed logical block address (LBA) ranges. Additionally, a controller is included in the device. The controller is configured to receive data extents addressed by a first LBA and a logical block count. The controller is also configured to identify at least one separately managed LBA range of the plurality of separately managed LBA ranges in the at least one cache memory based on LBAs associated with at least some of the received data extents. The controller stores the at least some of the received data extents in substantially monotonically increasing LBA order in at least one physical storage location, of the at least one cache memory, assigned to the identified at least one LBA range.

    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.
