    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: An access device 100 includes an access speed information part 112 for informing an access speed required for data recording by the access device 100 to a nonvolatile memory device 200. The nonvolatile memory device includes an access condition determination part 212 for determining an access condition required for meeting the informed access speed and an access area determination unit 213 for determining an access area according to the determined access condition. The access device 100 informs the required access speed to the nonvolatile memory device 200 in advance so that the access condition determination part 212 and the access area determination part 213 in the nonvolatile memory device 200 realize data recording which meets the access speed informed in advance upon the data recording. Thus, it is possible to access all the nonvolatile memory devices at a desired speed regardless of difference in characteristics of the recording speed of each of the nonvolatile memory devices.

    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 an access device accesses a nonvolatile memory device, the nonvolatile memory device or the access device detects or calculates a temperature T of the nonvolatile memory device. A temperature-adaptive control part of the nonvolatile memory device controls an access rate to a nonvolatile memory on the basis of the temperature T. Accordingly, the control part controls the rate so that the temperature T of the nonvolatile memory devices cannot exceed a limit temperature Trisk. In this manner, a nonvolatile memory system can eliminate a risk of a burn when ejecting the semiconductor memory device and can read and write data at a high speed.

    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.
