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.

Memory card

Memory system capable of controlling wireless communication function

According to one embodiment, a memory system includes an application module, a storage module, and a control module. The storage module stores user data, application software configured to control operation of the application module, and management information used to manage the user data and the application software. The control module controls writing and erasing of the storage module. The control module masks information indicating an access-prohibited area included in the management information read from the storage module, the access-prohibited area includes the application software.

Memory system capable of prohibiting access to application software and system software

According to one embodiment, an information processing apparatus includes a nonvolatile semiconductor memory and a processor. The nonvolatile semiconductor memory stores identification information. The processor controls an application which executes authentication processing for authenticating validation of the identification information stored in the nonvolatile semiconductor memory. The processor executes the application to read the identification information from the nonvolatile semiconductor memory, and to execute the authentication processing for determining whether or not the identification information is authentic. When the identification information is authentic, the processor continues at least some processes of the application, and when the identification information is inauthentic, the processor ends at least some processes of the application.
