Abstract: A storage device generates and stores a key stream and a value stream by extracting from data a plurality of keys and a plurality of values respectively corresponding to the plurality of keys. The storage device includes a controller and a non-volatile memory. The controller receives from a host information about an invalid key included in the key stream together with a compaction command, and performs a compaction operation on the key stream in response to the compaction command. The non-volatile memory stores the key stream and the value stream. The controller merges the key stream with another key stream based on the information about the invalid key in the compaction operation.

Abstract: A key-value storage device includes a non-volatile memory (NVM) divided into blocks, and a data buffer including a key buffer, a value buffer and a mapping buffer, and a controller including a key-value manager. The key-value manager receives a command and key-pairs including keys and values respectively corresponding to the keys, separates the keys from the values, store the keys in the key buffer and store the values in the value buffer, generates a value stream by combining a set of values stored in the key buffer, generates a key stream by combining a set of keys and merging indices for values respectively corresponding to the keys in the set of keys, and updates a key matrix stored in the mapping buffer and indicating whether an index among the indices of the key stream is related to each one of the blocks of the NVM.

Abstract: A storage device includes a controller configured to: receive, from a host, a plurality of key-value pairs, separate a key from each of the plurality of key-value pairs and a value therefrom, and generate a first key stream by merging a plurality of keys separated from the plurality of key-value pairs, and non-volatile memory configured to store the first key stream. The first key stream is stored, separately from the value separated from each of the plurality of key-value pairs, in the non-volatile memory.

Abstract: A storage device includes multiple memory devices and a memory controller. The memory controller receives, from a host, values corresponding to data stored in the memory devices and keys for identifying the values, generates parities for inspecting the data for any errors based on the values, and manages key-value mapping information regarding a correspondence between the values and the keys. The memory devices include a first memory device and a second memory device, which store the values and the keys, and a third memory device, which stores parity values calculated from the values and a parity value header for managing the parity values.
