Abstract: An information processing apparatus in which data is accessed every predetermined data amount, wherein when writing data transmitted from a host system side, in the case where the data is presumed to be continuous data constituting a single file, metadata indicating that the data from the host system side is continuous data is written along with the data.

Abstract: The efficiency of processing is increases even in a case where an area release notification issued to expressly specify release of an unnecessary area from a host side is inconsistent with a management unit of a storage. The storage controller receives at least one area release request for the storage from a host computer. Until predetermined conditions are met after the receipt of the area release request, the storage controller causes the storage to suspend a process on the area release request. When the predetermined conditions are met, the storage controller causes the storage to execute the process on the area release request.

Abstract: A storage device of the disclosure includes: a storage section that stores data; a communication section that performs wireless communication with one or a plurality of electronic apparatuses; an interface section that performs exchange of the data with a host apparatus; and a control section that determines a distance to each of the electronic apparatuses through the wireless communication, and controls access to the storage section by the host apparatus, on the basis of the distance and whether the host apparatus is accessing the storage section.

Abstract: A memory control device includes a control unit that performs data write/read control on a nonvolatile memory having at least a first area and a second area. In a case where writing sets of data into the first area, the control unit temporarily writes the sets of data into the second area. In a case where copying the respective sets of data written into the second area into the first area, the control unit sets a flag indicating whether the copying of the sets of data into the first area has been completed.
