Abstract: Systems and methods for host-assisted storage device error correction are described. A host may first encode host data with a forward error correction code (ECC) and send the encoded host data to the storage device. The storage device may further encode the host data using its own ECC. The host may also provide the forward ECC parity information to be stored on the storage device in a different location than the host data. When the host data is read by the storage device, the storage device will decode with its ECC. If the storage device ECC decode is incomplete and the bit error rate is below the recoverable error threshold of the forward error correction, the partially-recovered host data will be sent to the host. The host will complete decode using the forward ECC and parity data. Forward ECC may be selectively applied to important host data.

Abstract: Devices and methods are disclosed that transcode a media file to generate a transcoded file that is based on a codec preference of a client device. The transcoded file can then be used to replace the media file or added as an additional stream to the media file. The transcoded file is transmitted to the client device. The client device can request the media file with a list of prioritized codecs so that the transcoded file is transcoded using a codec from the list based on the priority of the codec.

Some host compute commands may include a scheduling tag. The storage device may operate in a storage processing state and an idle state and may selectively execute delayed host compute tasks during the idle state.

Abstract: A storage system and method for event-driven data stitching in surveillance systems are provided. In one embodiment, a storage system is provided comprising a memory and a controller.

Other embodiments are provided.

Abstract: Aspects of a multi-protocol storage device including a memory and a controller are provided which allow for endurance and other storage requirements of a host to be maintained for different logical regions of memory without disruption due to protocol switching. The memory includes blocks that are each associated with a storage attribute such as high endurance, performance, or protection. While operating in a first mode such as NVMe, the controller receives a mapping of storage attributes to different logical regions and stores the mapping in memory. The controller also associates blocks to logical addresses based on the mapping. When the controller switches to a second mode such as SD in response to a host command, the controller reads the mapping from memory and similarly associates blocks to logical addresses based on the mapping in the second mode. Storage attributes thus remain applicable across modes when mapping and storing data.

Other embodiments are provided.

Abstract: Various embodiments of this disclosure are directed to a mixed digital and analog domain approach to computational storage or memory applications. The mixed approach enables certain compute operations to be advantageously performed in the analog domain, achieving power saving. In some embodiments, an analog compute core is implemented based on a first set of memory elements that are made available with a second set of memory elements for digital data storage. A controller coupled to both sets of memory elements is able to selectively direct computational tasks to either the analog compute core or a digital processor coupled with the controller, based on one or more parameters including power, precision, and workload. In certain embodiments involving neural network tasks, the controller is configured to route certain tasks to the analog compute core based on neural network based factors such as network layer positioning and input signal type.

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.

Other embodiments are provided.

Abstract: A storage system and method for user-defined data archiving are provided. In one embodiment, the method comprises: receiving a write command from a host; determining whether the storage system received an indicator from the host indicating that data of the write command is archive data; in response to determining that the storage system received the indicator, storing the data in the multi-level memory cells; and in response to determining that the storage system did not receive the indicator, storing the data in the single-level memory cells. Other embodiments are provided.

Abstract: Aspects of a multi-protocol storage device including a controller are provided which handle mode switches after a shutdown resulting in a large amount of unfinished work by phasing the work during and after initialization. The controller operates in a first mode such as an SD mode and a second mode such as a NVMe mode. In the event of a shutdown in the second mode resulting in unfinished work, the controller initializes in the first mode. During initialization, the controller determines whether a completion time for the unfinished work exceeds an initialization time in the first mode. When the completion time exceeds the initialization time, the controller performs a first portion of the work during initialization and postpones performance of at least a second portion of the unfinished work until after initialization. As a result, initialization timeouts in the first mode due to the unfinished work may be avoided.

Abstract: Virtual physical erase of a memory of a data storage device. One example data storage device may include a flash memory. The data storage device further may include an electronic processor that may be configured to store a first portion of data in the flash memory, and receive a physical erase request from an access device. The electronic processor may be further configured to identify a first block of the flash memory and a memory fragment of the first block where the first portion of data is stored in the flash memory. The electronic processor may be further configured to, in response to receiving the physical erase request, program one or more cells corresponding to the memory fragment to an increased voltage state so as to obfuscate the first portion of data that is stored in the flash memory.

Abstract: A self-data-generating storage system and method for use therewith are provided. In one embodiment, a controller of the storage system is configured to receive a single video frame of video footage from a host; generate a plurality of video frames from an interpolation of the single video frame; and store the single video frame and the generated plurality of video frames in the memory. Other embodiments are provided.

Abstract: Aspects of a storage device including a memory and a controller are provided which optimize read look ahead (RLA) performance based on zone configurations or stored metadata. The controller stores in memory information previously received from a host, including a zone configuration or other information from which metadata associated with subsequent data to be pre-fetched in RLA may be determined. When the stored information includes the zone configuration, the controller reads data from memory in response to a host command and limits pre-fetching of subsequent data from the memory based on the zone configuration. When the stored information includes metadata, the controller reads the metadata associated with subsequent data from the memory, and limits pre-fetching of the subsequent data based on the metadata. Thus, resources of the storage device that are typically used for RLA may instead be used for other operations, improving the efficiency of the storage device.

Other embodiments are provided.

Other embodiments are provided.

Other embodiments are provided.
