  • Key-value storage device and method of operating the same
    Patent number: 11874815
    Abstract: A key-value storage device includes a non-volatile memory and a controller. The key-value storage device is configured to communicate with a host and includes a controller and a non-volatile memory. The controller is configured to receive, from the host, a first command including a key, a first chunk among multiple chunks included in a value corresponding to the key, and a first chunk index corresponding to the first chunk. The controller is configured to store mapping information of the first chunk in a mapping table based on the key and the first chunk index. The non-volatile memory is configured to store the key and the first chunk based on the mapping information.
    Type: Grant

  • Data storage device that stores multiple values corresponding to multiple keys in a page
    Patent number: 11112976
    Abstract: A data storage device includes a non-volatile memory, including a first region and a second region different from the first region, and a controller which stores first and second data in a first region of the non-volatile memory. The first region of the non-volatile memory includes first and second storage regions. A part of the first data is stored in the first storage region, and another part of the first data is stored in the second storage region. The second data is stored in the second storage region, and an offset value of the second storage region in which the second data is started is stored in the second region of the non-volatile memory.
