  • Patent number: 11537303
    Abstract: The present disclosure generally relates to creating new zones in a data storage device in a manner that ensures substantially even workload of the memory device storage locations. The data storage device can guide a host device to select a particular zone to open in zone namespace (ZNS) systems where the host device selects which zone to open. The data storage device tracks the workload of the various storage locations and create zones. The data storage device then provides selected zones having the least used storage locations with the idea of guiding the host device to select the zone having the least used storage locations. Thus, rather than utilizing a randomly selected unopened zone, the host will select, based upon guidance from the data storage device, zones that contain the least utilized storage location. In so doing, generally even workload of the memory device storage locations is achieved.

  • Patent number: 11537305
    Abstract: The present disclosure generally relates to creating new zones in a data storage device in a manner that ensures substantially even workload of the memory device storage locations. When receiving a zone open command in a zone namespace (ZNS) system, rather than randomly selecting an unopen zone, zones may be categorized based upon storage location workload so that any new zone that is opened utilizes the least utilized storage location. In so doing, generally even workload of the memory device storage locations is achieved.

  • Publication number: 20220399040
    Abstract: A data storage device and method for auto-peeling of surveillance video content to increase archival storage is provided. In one embodiment, a data storage device is provided comprising a memory and a controller. The controller is configured to determine that available storage space in the memory is less than a threshold; in response to determining that the available storage space in the memory is less than the threshold: read a video file from the memory; and re-encode the video file to decrease a size of the video file, wherein re-encoding the video file increases available storage space in the memory without deleting the video file. Other embodiments are provided.

  • Publication number: 20220308787
    Abstract: Aspects of a storage device including a memory and a controller are provided. The memory includes a plurality of non-volatile memory packages coupled to the switch, in which each non-volatile memory package includes a plurality of non-volatile memory dies. The controller can select a non-volatile memory package with the switch. The controller can establish a data channel connection between the selected non-volatile memory package and the controller via the switch. In some aspects, the selected non-volatile memory package is transitioned into an active mode and one or more non-selected non-volatile memory packages are each transitioned into a standby mode. The controller also can perform one or more storage device operations with one or more non-volatile memory dies of the plurality of non-volatile memory dies within the selected non-volatile memory package. Thus, the controller may facilitate a switch based ball grid array extension, thereby improving memory capacity of the storage device.

  • Publication number: 20220129388
    Abstract: A non-volatile storage system includes a memory controller connected to an integrated memory assembly. The integrated memory assembly includes a memory die comprising non-volatile memory cells and a control die bonded to the memory die. The memory controller receives commands from a host, performs logical address to physical address translation (“address translation”) operations for the commands, and instructs the integrated memory assembly to perform one or more operations in support of the command. The control die also includes the ability to perform the address translation. When performing a command from the host, the memory controller can choose to perform the necessary address translation or instruct the control die to perform the address translation. When the control die performs the address translation, the resulting physical address is used by the control die to perform one or more operations in support of the command.
