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. ## Claims ### Claim 1 A controlling method of a memory card, the memory card comprising: a nonvolatile semiconductor memory; a controller configured to control the nonvolatile semiconductor memory; a memory serving as a work area of the controller; a wireless communication module having a wireless communication function; and an extension register to be provided in the memory and including a plurality of pages, wherein each of the plurality of pages has a data length defining the wireless communication function, the method comprising: processing a first command to read data from the extension register, and a second command to write data to the extension register; and recording 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; wherein the extension register, to which the wireless communication function is assigned, comprises: a first register which indicates the wireless communication function to support; a second register for writing a third command to perform a wireless communication; a third register for reading a processing state of the third command; and a fourth register for reading an execution result of the third command. ### Claim 2 (depends on 1) The method according to claim 1, wherein the first command is a command to read data from the extension register in unit of a page, and the second command is a command to write data to the extension register in a unit of a page. ### Claim 3 (depends on 1) The method according to claim 1, wherein the first command, the second command, and the third command include a register select indicating a page in the extension register and an offset indicating a position of data in the selected page. ### Claim 4 (depends on 1) The method according to claim 1, wherein the first command, the second command, and the third command include an information indicating the data length. ### Claim 5 (depends on 1) The method according to claim 1, wherein the extension register includes a data port for writing the third command and an argument. ### Claim 6 (depends on 1) The method according to claim 1, Wherein the extension register includes a data port for acquiring a response as an execution result of the third command.
