Abstract: A method of managing data in a storage device is provided. The storage device includes a plurality of nonvolatile memory chips each including a plurality of pages. A first data object is received from an external host device. The first data object has an unfixed size and corresponds to a first logical address which is a single address. Based on determining that it is impossible to store the first data in a single page among the plurality of pages, a buffering policy for the first data object is set based on at least one selection parameter. While mapping the first logical address of the first data object and a first physical address of pages in which the first data object is stored, a first buffering direction representing the buffering policy for the first data object is stored with a mapping result.

Abstract: A key-value storage device includes a nonvolatile memory device and a memory controller. The nonvolatile memory device stores a value, a key which is referenced to identify the value, and key age data which are changed based on an erase operation of the value, and the memory controller that receives an erase command directing erasing of the value corresponding to the key from a host, generates hash data, a size of which is smaller than a size of the key, in response to the erase command, and transmits a complete message to the host. The memory controller accesses the key and the key age data stored in the nonvolatile memory device based on the hash data and erases the value based on the accessed key and the accessed key age data during an idle time after the transmission of the complete message.

Abstract: A storage system performing an overwrite, a host system controlling the storage system, and an operating method of the storage system, wherein the storage system includes a memory device; and a controller that receives new data and an overwrite request from the host system, wherein the overwrite request includes a first logical address for old data and a second logical address for the new data, and performs an overwrite operation by writing the new data corresponding to the second logical address to the memory device and invalidating the old data corresponding to the first logical address according to the overwrite request.

Abstract: A computing system includes a storage system configured to store data, and a host configured to compress a data block of a preset size loaded to a memory, generate a merged block of the preset size by merging a compressed block corresponding to the data block, an identifier of a node block referring the data block, and an offset indicating an index of the data block among at least one data block referred by the node block, and provide the merged block to the storage system.
