摘要:
According to one embodiment, a memory system including a key-value store containing key-value data as a pair of a key and a value corresponding to the key, includes an interface, a memory block, an address acquisition circuit and a controller. The interface receives a data write/read request or a request based on the key-value store. The memory block has a data area for storing data and a metadata table containing the key-value data. The address acquisition circuit acquires an address in response to input of the key. The controller executes the data write/read request for the memory block, and outputs the address acquired to the memory block and executes the request based on the key-value store. The controller outputs the value corresponding to the key via the interface.

According to one embodiment, a storage device includes an interface, a first and second memory blocks and a controller. The interface receives a content search request. The first memory block stores files and inverted files corresponding to contents included in the files. The second memory block stores a file search table. The controller creates the inverted file for each content included in the files and stores IDs of the files including the content in the inverted file. The controller obtains, by search of the content, a corresponding inverted file from the inverted files stored in the first memory block and stores, in the file search table, the IDs of the files included in the obtained inverted file. The controller outputs the IDs of the files stored in the file search table from the interface as a search result for the content search request.
