摘要： A file to be read or written is designated and accessed from an access device side to a nonvolatile memory device. In an initialization after start-up of the power source, an empty capacity detector detects empty capacity parameters of a nonvolatile memory with dividing the memory into a plurality of regions. An empty capacity parameter notification part notifies the access device of the empty capacity parameters in a stepwise fashion whenever the empty capacity detector detects an empty capacity. With this, at the time when the empty capacity becomes not less than a capacity required to write file data, the data can be written to the nonvolatile memory without waiting for completion of the initialization, resulting in improvement of a response in the recording.

摘要： A nonvolatile memory device reads and writes file data according to a file ID designated by an access device. The nonvolatile memory device includes a capacity parameter decision part 260 which generates a capacitance parameter related to a usable capacity of a nonvolatile memory 210. Even if a defective region of the nonvolatile memory is gradually increased as the use is continued, a capacity parameter decision part 161 reduces a normal region in accordance with increase of the defective region. The capacity parameter notification part notifies the reduced capacity parameter to the access device. Based on the notified capacity parameter, the access device manages the total size of all the files to be read and written.

摘要： A nonvolatile memory device has a file system manager and manages the file system of a file to be recorded. The nonvolatile memory device measures time by obtaining time information from outside in each writing file data or based on time information preliminarily obtained. At the time of writing file data, management information of the file system is configured based on the time information at the time. Thus, the time information can be stored in a file entry table, and the time information can be used as file management information. The nonvolatile memory system with high user's convenience can be provided.

摘要： A host device (1) adds host function information indicating a function of the host device (1) to a command and transmits it to a storage device (2). The storage device (2) receives the command transmitted from the host device (1) and determines whether the function indicated by the host function information can be processed. When the function can be processed, the function is processed based on the command. When the function cannot be processed, no response is returned or error information is returned. Thus, under simple control, it is possible to prevent data destruction by a host device of an old version.
摘要翻译：主机设备（1）将指示主机设备（1）的功能的主机功能信息添加到命令中，并将其发送到存储设备（2）。存储装置（2）接收从主机装置（1）发送的命令，并且确定是否可以处理由主机功能信息指示的功能。当功能可以处理时，该功能将根据该命令进行处理。当函数无法处理时，不返回任何响应或返回错误信息。因此，在简单的控制下，可以防止主机装置破坏老版本的数据。

摘要： Without corresponding to different address spaces between an access device (100) and a nonvolatile memory device (200), the access device (100) designates a file ID to manage a data storing state only in a physical address space in the nonvolatile memory device (200). The access device (100) sends the nonvolatile memory device (200) a transfer rate through a transfer rate transmitting unit (121). A filling-up rate calculating unit (251) calculates a filling-up rate of a physical block corresponding to an assurance speed required by the access device (100). A remaining amount corresponding to the transfer rate is sought by using the calculated rate and is transmitted to a remaining amount receiving unit (122) of the access device (100).

摘要： When a file system control part 155A writes file data into a main memory 142, a file can be easily written continuously and the number of file copy can be decreased at updating a directory entry by writing the file data and a directory entry into different allocation units. In this manner, when using a nonvolatile memory in which physical block size as an erase unit is larger than cluster size, the write performance can be enhanced.
摘要翻译：当文件系统控制部分155A将文件数据写入主存储器142时，可以容易地连续地写入文件，并且可以通过将文件数据和目录条目写入不同的分配单元来更新目录条目来减少文件拷贝的数量。以这种方式，当使用物理块大小作为擦除单位的非易失性存储器大于簇大小时，可以提高写入性能。
