A memory system includes a non-volatile semiconductor memory device, a control unit, a memory as a work area, a wireless communication module, and an extension register. 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.

Memory system allowing host to easily transmit and receive data

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. The extension register is provided in the memory. The controller processes a first command to read data from the extension register, and a second command to write data to the extension register. The extension register records, an information specifying the type of the wireless communication function in a specific page, and an address information indicating a region on the extension register to which the wireless communication function is assigned.

Controlling method of a memory card

According to one embodiment, a memory system includes a non-volatile semiconductor memory device, a control unit, a memory as a work area, a wireless communication module, and an extension register. 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.

According to one embodiment, a storage device includes a non-volatile memory, an interface circuit, a first control circuit, a wireless transmitting and receiving circuit, and a second control circuit. The interface circuit is electrically connected to the host device and is capable of communicating the host device. The first control circuit performs control of writing write data received from the host device via the interface circuit into the non-volatile memory. The wireless transmitting and receiving circuit is capable of wirelessly communicating with a wireless device. The second control circuit determines whether or not the write data include a predetermined type of data based on measurement data of the write data, and stops wireless communication performed by the wireless transmitting and receiving circuit if it is determined that the write data include the predetermined type of data.

Wireless communication enabled storage device and control method therefor

Memory card

A memory device includes a non-volatile memory and a controller. The controller is configured to control the non-volatile memory and includes a receiving circuit configured to receive first data from an external device, a converting circuit configured to convert the first data received by the receiving circuit to second data having a data size equal to or smaller than a data size of the first data, and a writing circuit configured to write the second data converted by the converting circuit in the non-volatile memory.
