Patent number: 12003776Abstract: A storage device is configured to reduce the file size of media files stored on the device by removing thumbnail data. In response to determining that a data file received from a host is a media file having thumbnail data and a file size, the control circuitry is configured to modify the media file to remove the thumbnail data and reduce the file size of the media file, and then store the modified media file. In response to receiving a request for the data file from the host, the storage device responds by retrieving the modified media file from the storage medium, generating second thumbnail data corresponding to the original thumbnail data, remodifying the media file to add the second thumbnail data to the request; and providing the remodified media file to the host.Type: GrantFiled: December 28, 2021Date of Patent: June 4, 2024Assignee: Western Digital Technologies, Inc.Inventors: Govind Kumar Mangal, Eldhose Peter, Rakesh Balakrishnan

Publication number: 20230409239Abstract: A request to perform a memory access operation at a zone of a memory device is received from a host system. An identifier of the memory access operation is stored in a first queue of the memory device. A plane set that is associated, by a memory data structure, with the zone of the memory device is identified among a plurality of plane sets of the memory device. Responsive to retrieving the identifier of the memory access operation from the first queue, the identifier of the memory access operation is stored in a second queue of the memory device, wherein the second queue corresponds to the identified plane set. Responsive to retrieving the identifier of the memory access operation from the second queue, the memory access operation is performed at the zone of the memory device.Type: ApplicationFiled: June 21, 2022Publication date: December 21, 2023Inventor: Eldhose Peter

Patent number: 11823766Abstract: A storage device is provided that allows a controller to directly access bytes of data in data latches connected to memory, as opposed to through controller RAM. The storage device may include a memory, a plurality of data latches connected to the memory, and a controller coupled to each of the data latches. The controller is configured to access one or more bytes of decoded data in one or more of the data latches. For instance, the controller may provide a command including an address for data in the memory, and may process one or more bytes of the data in at least one of the data latches in response to the command. The controller may also store a mapping of addresses for each of the word lines, including the address provided in the command. As a result, operation latency may be reduced and controller RAM savings achieved.Type: GrantFiled: November 15, 2021Date of Patent: November 21, 2023Assignee: WESTERN DIGITAL TECHNOLOGIES, INC.Inventors: Akhilesh Yadav, Eldhose Peter, Rakesh Balakrishnan

Patent number: 11675528Abstract: 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.Type: GrantFiled: March 29, 2021Date of Patent: June 13, 2023Assignee: WESTERN DIGITAL TECHNOLOGIES, INC.Inventors: Akhilesh Yadav, Ramanathan Muthiah, Eldhose Peter

Patent number: 11650932Abstract: 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.Type: GrantFiled: February 17, 2021Date of Patent: May 16, 2023Assignee: Western Digital Technologies, Inc.Inventors: Rakesh Balakrishnan, Eldhose Peter, Akhilesh Yadav, Ramanathan Muthiah, Vimal Kumar Jain

Patent number: 11537305Abstract: 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.Type: GrantFiled: June 3, 2021Date of Patent: December 27, 2022Assignee: Western Digital Technologies, Inc.Inventors: Ramanathan Muthiah, Rakesh Balakrishnan, Eldhose Peter, Judah Gamliel Hahn

Patent number: 11537303Abstract: 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.Type: GrantFiled: June 3, 2021Date of Patent: December 27, 2022Assignee: Western Digital Technologies, Inc.Inventors: Ramanathan Muthiah, Rakesh Balakrishnan, Eldhose Peter, Judah Gamliel Hahn
