  • Storage device with multi-die management
    Patent number: 10656872
    Abstract: An example of a system includes a plurality of non-volatile memory dies, a memory bus coupled to the plurality of non-volatile memory dies, and one or more control circuits coupled to the plurality of non-volatile memory dies through the memory bus. The one or more control circuits include a plurality of die-specific request queues configured in a one-to-one correspondence with the plurality of non-volatile memory dies. The one or more control circuits are configured to add die-specific atomic requests to individual die-specific request queues of the plurality of die-specific request queues independently of each other in response to die-specific triggering events.
    Type: Grant

    Date of Patent: May 19, 2020
    Assignee: Western Digital Technologies, Inc.
    Inventors: Lee Gavens, Yoav Weinberg, Meiqing He

  • Memory bus management
    Patent number: 9734098
    Abstract: A method of managing a memory bus includes identifying sub-operations required for execution of commands, maintaining a list of released sub-operations containing only released unexecuted sub-operations directed to individual dies that are identified as available, accessing the dies until the list is empty, subsequently, polling to identify dies that are available, and subsequently resuming accessing the dies by executing only sub-operations from the list until the list is empty.
