    Abstract: Certain exemplary aspects of the present disclosure are directed towards methods and apparatuses in which logic circuitry generates an error detection code based on user data received from a host, and further generates a first set of check bits, to be written to the non-volatile memory circuit in conjunction with the user data, by combining the error detection code with a hashed data address of the user data. In some embodiments, the check bits associated with the user data providing verification that the user data was written in the appropriate physical block address of the non-volatile memory circuit.

    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: A data storage device includes a storage tier and a storage controller operably coupled to the storage tier and configured to be communicatively coupled to a host device. The storage controller includes a first memory operably coupled to the storage controller and configured to store a superseding data structure. The storage controller further includes a second memory operably coupled to the storage controller and configured to store a forward map configured to map a plurality of logical block addresses to physical locations on the storage tier. The storage controller further includes a sifting module configured to sift the forward map based on data contained in the superseding data structure. The storage controller further includes a compression module configured to compress the forward map to generate a compressed forward map.

    Abstract: A device includes one or more data storage media having a main storage area, and includes a non-volatile cache memory and a controller. The controller stores a plurality of data packets into a plurality of physical locations in the main storage area. Each of the data packets is associated with a different logical block address (LBA), and each of the physical locations is associated with a different physical location address (PLA). The controller generates mapping information that links the different LBAs to the different PLAs. Upon detecting a soft error when reading a data packet stored in a physical location, the controller relocates the data packet associated with the soft error to a physical location of the non-volatile cache memory. The controller also marks the physical location as a suspect location. The controller updates the mapping information to reflect the relocation of the data packet associated with the soft error.
