  • Efficient data storage usage associated with ungraceful shutdown
    Patent number: 11416058
    Abstract: The present disclosure generally relates to efficient block usage after ungraceful shutdown (UGSD) events. After a UGSD event, a host device is alerted by the data storage device that a QLC block that was being used prior to the UGSD event is experiencing an ongoing block recovery and that the block is not yet available to accept new data. The block is then checked to determine whether the block can continue to be used for the programming that was occurring at the time of the UGSD event. Once a determination is made, the data storage device notifies the host device so that normal operations may continue. Additionally, the amount of free blocks available for programming is monitored during UGSD events so that the host device can be warned if a power loss halt is triggered.

  • DETECTION OF COMPROMISED STORAGE DEVICE FIRMWARE
    Publication number: 20220245242
    Abstract: An apparatus, system, and method for detecting compromised firmware in a non-volatile storage device. A control bus of a non-volatile storage device is monitored. The non-volatile storage device includes a processor and electronic components coupled to the control bus. Signal traffic on the control bus is analyzed for events and/or triggers related to storage operations initiated on the control bus by the processor. Storage operations include one or more commands directed to at least one of the electronic components. If the latency for the storage operation satisfies an alert threshold a host is notified of compromised firmware.

  • Early Transition To Low Power Mode For Data Storage Devices
    Publication number: 20220229566
    Abstract: The present disclosure generally relates to data storage devices, such as solid state drives, and effective power management of the data storage device. The data storage device includes a controller, where the controller is configured to predict when a host device will send a command to enter a low power state, prepare the data storage device to enter the low power state, and receive a command to enter the low power state after the predicting and preparing. If the data storage device is idled for greater than a threshold value, then the data storage device prepares to transition to a low power state but will wait to enter the lower power state until receiving a request from a host device.

  • DRAM-less SSD With Command Draining
    Publication number: 20220229586
    Abstract: A data storage device includes one or more memory device and a controller that is DRAM-less coupled to the one or more memory devices. The controller is configured to receive a command from a host device, begin execution of the command, and receive an abort request command for the command. The command includes pointers that direct the data storage device to various locations on the data storage device where relevant content is located. Once the abort command is received, the content of the host pointers stored in the data storage device RAM are changed to point to the HMB. The data storage device then waits until any already started transactions over the interface bus that are associated with the command have been completed. Thereafter, a failure completion command is posted to the host device.

  • Zone-append command scheduling based on zone state
    Patent number: 11372543
    Abstract: The present disclosure generally relates to scheduling zone-append commands for a zoned namespace (ZNS). Rather than taking zone-append commands in order or randomly, the zone-append commands can be scheduled in the most efficient manner consistent with the open zones of the ZNS. A zone priority is determined based upon the length of time that a zone has been open together with the zone status. Generally, the older the zone and/or the more full that a zone is increases the priority. Once the zone priority is established, the zone-append commands are scheduled to ensure the zone-append commands for the high priority zones are processed first so that the open zone can be filled prior to closing.

  • AUTOMATIC FLEXIBLE SCHEMA DETECTION AND MIGRATION
    Publication number: 20220147497
    Abstract: A method and apparatus for automatic schema detection and migration is disclosed. In embodiments, a file including NoSQL data is received and one or more data types are detected in a hierarchical data table description. Within a record of the NoSQL data, which may be stored in a JSON format, a field name and its data type, are stored in a schema describing the data table. As additional records are parsed, the schema is updated to include additional field names and data types, and may include designations such as repeated and optional, for some fields. In embodiments, the schema is a serialized data format, such as Google Protocol Buffers (Protobuf).

  • DATA STORAGE DEVICE DATABASE MANAGEMENT ARCHITECTURE
    Publication number: 20220147249
    Abstract: A method and apparatus for a database management architecture on an SSD. A list of tables is stored in the SSD, and records of a table are stored across multiple FIMs of the SSD such that a group of records may be read in parallel by concurrently reading from multiple FIMs. The records of the table are stored on jumboblocks, organized in an unordered fashion as a linked list. New records are added to the end of the linked list. Records having gaps resulting from data modification or bad portions of an NVM die are re-organized via garbage collection when the gap memory size reaches about 20% of table memory size.

  • QUERY COMPILER FOR RECORD FILTERING
    Publication number: 20220121661
    Abstract: A method and apparatus for carrying out a database select, or query, on a data storage device, upon data stored on that device. Data is received from a host and compressed on the data storage device using a compression code developed on the data storage device for the data. When the host issues a database select request on the compressed data, the compression code is distributed to processing cores of the data storage device and compiled, including the select request, into machine code. The machine code is used to decompress the compressed data while filtering the data with the select request. The filtering result is returned to the host.

  • EMULATION OF CODE-DESCRIPTION TABLES ON SQL DATABASES USING ENUM DATA TYPE
    Publication number: 20220121618
    Abstract: A method and apparatus for converting code-description table data to an enumerated data type in a schema record referencing the code-description table. A record of a table is identified that references the code-description table, and a portion of a schema describing the record is updated to include the relevant data of the code-description table as an enumerated type of the record schema. The enumerated type schema element includes data elements of the code-description table relevant to the record, each element having its own type. As additional records of the same table that are related to the code-description table are called, the enumerated type schema element may be updated to include additional code-description table data elements.

  • Delayed write failure logging
    Patent number: 11294807
    Abstract: The present disclosure generally relates to a method and device for reduce the amount of energy used to revert data within a storage device to a consistent state after a power loss event. Once power is lost from a host device, and prior to complete shutdown, a log is created within non-volatile memory (NVM) of the storage device. The log contains logical block addresses (LBAs) corresponding to data that experienced a write failure. At the next power-on event, the log is checked to see if any LBAs are present. If LBAs are present in the log, then the data that experienced a write failure can be properly written to the storage device.
