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

A controller assigns a first plurality of blocks among a plurality of blocks provided in a non-volatile memory to a first area, assigns a second plurality of blocks to a second area, and assigns a third plurality of blocks to a third area. The controller uses each block assigned to the first area in a first mode, uses each block assigned to the second area in a second mode in which the number of bits of data written in each memory cell is larger than that in the first mode, and uses each block assigned to the third area in the first mode or the second mode. The controller writes data received from a host device to an area that corresponds to a designation from the host device out of the first area and the third area. The controller transcribes valid data written to the first area and the third area to the second area.

Memory system having two or more write modes

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.
