Abstract:
1. A memory system, comprising: a nonvolatile memory area comprising a first area configured to allow a write-in action and a read-out action to be performed on data by a first host device and a second host device, and a second area configured to retain a first wireless communication configuration to connect to the second host device via wireless communication and configured to prohibit a write-in action and a read-out action to be performed on data by the first host device and the second host device; a first interface configured to connect to the first host device; a second interface configured to connect to the second host device via wireless communication; and a controller configured to connect to the second host device using the first wireless communication configuration in a case that the controller determines a second wireless communication configuration to connect to the second host device is not retained in the first area, the controller controlling the first interface so that the first host device is configured to not write data into the memory area on a basis of a command provided from the second host device, when the controller changes the first wireless communication configuration via the second host device, the controller copying the first wireless communication configuration into the first area after the first interface is controlled so that the first host device is configured not to write data into the memory area, generating the second wireless communication configuration by changing the first wireless communication configuration copied in the first area, and connecting to the second host device using the second wireless communication configuration; wherein the first interface notifies an error to the first host device when the first host device performs the write-in action to the memory area, in a case that the first interface is controlled so that the first host device is configured not to write data into the memory area.
