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.

Provided is a method capable of performing bi-directional communication by only a memory card device and without depending on the environment of the connecting device and the like. This memory card device has a housing in which a wireless communication module and memory module are mounted, and in the this memory module are provided a system area that cannot be access by a digital device in which the memory card device is mounted, and a user area that can be accessed by the digital device; wherein an operation system (OS), a file server program that operates together with the operation system to control data that is stored in the user area, and a communication module that connects the server program to a virtual network by way of a relay server on the Internet, and makes it possible to control the data that is stored in the user area from the Internet side by way of the server program are installed in the system area.

This information processing system uses a simple configuration to control a remote device by employing a unified communication channel (pipe) from an application to the device. The information processing system is provided with: a device; a device control unit for controlling the device; a device interface unit for interfacing with the device control unit; an information processing device provided with an application, and an application interface unit for interfacing with the application; and a channel establishment unit which connects, via a communication unit, the application interface unit and the device interface unit, and establishes a control channel and a data channel between the application and the device.

Various embodiments comprise devices to manage multiple memory types and reconfigure partitions in a memory device as directed by a host. In one embodiment, the apparatus is to manage commands through a first interface controller to mapped portions of a first memory not having an attribute enhanced set, and map portions of a second memory having the attribute enhanced set through a second interface controller. Additional devices are described.

A method for reading/writing a chip in a USB type-C cable comprises converting a read/write command into unstructured vendor defined message (UVDM) that is conforming to a USB power delivery specification. Such UVDM will be delivered to the chip via a type-C configuration channel interface. The chip analyzes the UVDM to acquire the read/write command and reads or modifies the content of a non-volatile memory in the chip according to the read/write command. Due to use of the type-C configuration channel interface, which is inherent in the USB type-C cable, to read/write the chip, it needs no extra interface which otherwise increases costs.

The present invention provides a method performed by a secure digital (SD) card supporting both an SD mode and a peripheral component interconnect express (PCIe) mode for initializing the SD card. The method includes: (a) after receiving a first supply voltage through a first voltage supply pin from a host coupled to the SD card, entering the SD mode if the SD card is not in the PCIe mode and a CMD0 command for entering the SD mode is received through a command pin from the host coupled to the SD card; and (b) after receiving the first supply voltage through the first voltage supply pin from the host coupled to the SD card, performing a PCIe linkup process if the SD card is not in the SD mode and a second supply voltage is received through a second voltage supply pin from the host coupled to the SD card. The SD card enters the PCIe mode if the PCIe linkup process succeeds.
