Embodiment approach 1

[0036] Hereinafter, embodiments of the present disclosure will be described with reference to appropriate drawings.

[0037] However, in the detailed description, unnecessary parts in the description related to the prior art and substantially the same configuration are also omitted. This is for simplicity of illustration.

[0038] In addition, the following description and attached drawings are disclosed for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter of patent claims.

[0039]

[0040] figure 1 It is a figure which shows the structure of the access system in Embodiment 1 of this invention. The access system includes a wireless memory access device 1 as an example of an access device, and a wireless memory recording device 2 as an example of a device device. The wireless memory recording device 2 includes a nonvolatile memory 27 as an additional device. An add-on device is a device that imparts a g...

Embodiment approach 2

[0142] A second embodiment of the present disclosure will be described. This embodiment differs from Embodiment 1 in the processing procedure of "memory characteristic information reference processing", and other configurations and operations are the same as Embodiment 1. Therefore, in this embodiment, only the processing procedure of "memory characteristic information reference processing" will be described, and description of other processing procedures will be omitted.

[0143] Figure 9 It is a sequence diagram showing the processing procedure of "memory characteristic information reference processing" in this embodiment. In the present embodiment, the timing of memory property information reference in the "memory property information reference process" is different from that in the first embodiment. The specific processing procedure of the "memory characteristic information reference process" in this embodiment is as follows.

[0144] However, in the remote memory init...

Abstract

A functional device can communicate with an access apparatus. The functional device includes an access controller that controls an additional device and obtains characteristic information of the additional device at an initialization process of the additional device, a memory that stores the obtained characteristic information, a communication unit that transmits and receives data to and from the access apparatus, and a communication controller that transmits the characteristic information stored in the memory to the access apparatus, when receiving a request for the initialization process from the access apparatus through the communication unit after transferring an exclusive right to the access apparatus, the exclusive right being a right to exclusively control the additional device.

Description

technical field [0001] The present disclosure relates to a device device that processes a given function, an access device that controls the device device through a communication connection to the device device, and an access system including the access device and the device device. Background technique [0002] There are various types of recording media for recording digital data such as music content and video data, such as magnetic disks, optical disks, and magneto-optical disks. Among these recording media, a memory card using a semiconductor memory such as a flash memory as a recording element has rapidly spread mainly in small portable devices such as digital still cameras and mobile phone terminals due to the miniaturization of recording media. Furthermore, recently, not only is it used as a detachable removable medium like a conventional memory card, but also a semiconductor memory such as a flash memory is built into a device and used instead of a hard disk. Applic...
