  • Patent number: 10969963
    Abstract: A computer storage device having a host interface, a controller, non-volatile storage media, and firmware. The firmware instructs the controller to: receive, via the host interface, a request from a host to allocate a namespace of a quantity of non-volatile memory; generate, in response to the request, a namespace map identifying a plurality of blocks of addresses having a same predetermined block size, and a partial block of addresses having a size smaller than the predetermined block size; and convert, using the namespace map, logical addresses in the namespace communicated from the host to physical addresses for the quantity of the non-volatile memory. For example, the request for allocating the namespace can be in accordance with an NVMe protocol.

  • Patent number: 10936249
    Abstract: A memory system having a stack memory, a set of media, and a controller. The controller divides the stack memory into a plurality of stacks, measures usages of the stacks in a period of time of operating on the set of media, and adjusts partitioning of the stack memory into the plurality of stacks according to the measured usages.

  • Publication number: 20210048947
    Abstract: A data storage system having non-volatile media, a buffer memory, a processing device, and a data pre-fetcher. The data pre-fetcher receives commands to be executed in the data storage system, provides the commands as input to a predictive model, obtains at least one command identified for pre-fetching, as output from the predictive model having the commands as input. Prior to the command being executed in the data storage device, the data pre-fetcher retrieves, from the non-volatile memory, at least a portion of data to be used in execution of the command; and stores the portion of data in the buffer memory. The retrieving and storing the portion of the data can be performed concurrently with the execution of many commands before the execution of the command, to reduce the latency impact of the command on other commands that are executed concurrently with the execution of the command.

  • Patent number: 10915440
    Abstract: A computer storage device having a host interface, a controller, non-volatile storage media, and firmware. The firmware instructs the controller to: store a namespace map to map blocks of logical addresses defined in a namespace to first blocks of logical addresses defined in a capacity of the non-volatile storage media; without changing a size of the namespace, adjust the namespace map to map the blocks of the logical addresses defined in the namespace to second blocks of the logical addresses defined in the capacity of the non-volatile storage media (e.g., to consolidate blocks for performance improvement); and translate the logical addresses in the namespace to physical addresses for the non-volatile storage media using the namespace map.

  • Publication number: 20200411130
    Abstract: A memory system having non-volatile media and a controller configured to process requests from a host system to store data in the non-volatile media or retrieve data from the non-volatile media. The non-volatile media has a set of memory units. The memory system stores an indicator indicating whether the memory system is operating in a user mode or a manufacturing mode. A defect manager of the memory system identifies a threshold based on the indicator, monitors an error rate in reading data from the non-volatile media and, in response to the error rate reaching the threshold, screens the non-volatile media for defective memory units.

  • Publication number: 20200401353
    Abstract: A memory system having a mode indicator, a set of hardware resources, a set of media, and a controller. When the mode indicator identifies a factory mode, a first portion of the hardware resources is reserved for performance of factory functions by the controller and a second portion of the hardware resources is allocated for performance of normal functions. When the mode indicator identifies a user mode, both the first portion and the second portion are allocated for the performance of the normal function. The normal functions are performed by the controller to at least store data in and retrieve data from the set of media in response to requests from a host system.

  • Publication number: 20200341870
    Abstract: A memory sub-system having non-volatile media on which multiple namespaces are allocated. A command from a host system has an identification of a namespace and at least one error recovery parameter. A controller of the memory sub-system configures the namespace on the non-volatile media according to the at least one error recovery parameter, stores the at least one error recovery parameter in association with the namespace, and controls error recovery operations for data access in the namespace in accordance with the at least one error recovery parameter stored in association with the namespace.

  • Publication number: 20200301592
    Abstract: A computer system having a host coupled to a storage device via a peripheral component interconnect express bus. The host communicates with the storage device in accordance with a non-volatile memory host controller interface specification. The host provides a customized module containing instructions for performing the operations of a customized command. The host sends an idle time command to the storage device for execution at an idle time. In response to a determination that the storage device is in an idle state, the storage device executes the idle time command, during which the module may be used by the controller of the storage device.
