The control unit controls the non-volatile semiconductor memory device. The extension register is provided in the memory and has a data length by which a wireless communication function of the wireless communication module can be defined. The control unit causes the non-volatile semiconductor memory device to store, as a file, an HTTP request supplied from a host, causes the extension register, based on a first command supplied from the host, to register an HTTP transmission command transmitted together with the first command, and causes the wireless communication module to transmit the HTTP request stored in the non-volatile semiconductor memory device based on the transmission command registered in the extension register.

Abstract: According to an embodiment, a memory device includes a nonvolatile first memory, a nonvolatile second memory, a first controller, and a second controller. The first controller is configured to write, to the first memory, data received over a short-range radio communication by using power generated in the short-range radio communication. The second controller is configured to execute, at a startup of the memory device, a transfer process of reading a file written in the first memory and storing the read file to the second memory.

Abstract: According to one embodiment, a memory device includes a nonvolatile semiconductor memory, a control unit and a wireless communication unit. The control unit controls the nonvolatile semiconductor memory. The wireless communication unit includes a wireless communication function and is controlled by the control unit. The control unit includes a first control mode to control the wireless communication unit in accordance with set information when a control command to control the wireless communication unit is not received within a predetermined time. The control unit includes a second control mode to control the wireless communication unit in accordance with the control command when the control command is received within the predetermined time.

Abstract: An aspect of the present embodiment, there is provided a memory system including a nonvolatile memory area, a first interface be connected to a first host device, a second interface connected to a second host device, and a controller controlling the first interface such that the first device is configured to prohibit to write data into the nonvolatile memory area on a basis of a command provided from the second host device before the second host device writes data into the nonvolatile memory area through the second interface, wherein the first interface notices an error to the first host device when the first device writes data into the nonvolatile memory area, and the second host device transmits data from an portion not to be written in the nonvolatile memory area to the first host.

Abstract: A memory system includes a nonvolatile memory area including a first area in which write-in and read-out actions on data are performed and a second area in which such actions are prohibited, first and second interfaces, and a controller configured to connect to a second host using a first wireless communication configuration when 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 in so that the first host device writes 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, the controller connects to the second host device using the second wireless communication configuration, and the first interface notifies an error to the first host device not to write data into the memory area.

Abstract: According to one embodiment, a memory system includes a nonvolatile semiconductor memory device, controller, memory, wireless communication function section, and extension register. The controller controls the nonvolatile semiconductor memory device. The memory is serving as a work area of the controller. The wireless communication module has a wireless communication function.
