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.

Abstract: Provided is a storage device including a non-volatile memory including a first memory block and a second memory block different from the first memory block, and a memory controller configured to receive, from a host, a first write mode command corresponding to the first memory block and a second write mode command corresponding to the second memory block, control the first memory block to perform a first write operation according to the first write mode command, and control the second memory block to perform a second write operation according to the second write mode command, both the first write operation and the second write operation being sequential write operations.

Abstract: A method of operating a key-value storage device includes a key-value storage device receiving from a host a first command including a first key, a first value, and a first snapshot identification (ID), the key-value storage device generating a first snapshot entry including the first snapshot ID, the first key, and a first physical address in a non-volatile memory device at which the first value is written, in response to the received first command, receiving from the host a second command including the first key, a second value, and a second snapshot ID, and in response to the received second command, the key-value storage device generating a second snapshot entry including the second snapshot ID, the first key, and a second physical address in the non-volatile memory device at which the second value is written.
