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.

According to one embodiment, there is provided a memory card including a first surface, a second surface, and 1.sup.st to N.sup.th terminal groups. The first surface includes first to N.sup.th rows, where N is an integer of two or greater. The second surface faces the opposite side from the first surface. The 1.sup.st to N.sup.th terminal groups are placed in the first to N.sup.th rows. The 1.sup.st terminal group includes terminals to which differential clock signals are assigned, terminals to which single-ended signals are assigned, and a terminal to which a first power supply voltage is assigned. K.sup.th terminal group, where K is an integer no smaller than two and no greater than N, includes terminals to which differential data signals are assigned.

A portable data accessing device and more particularly the use of multi-port interfaces on a data accessing device disclosed. The multi-port data accessing device includes an inner body, one or a plurality of moving-caps, one or a plurality of grips, a pump-action and one or a plurality of locking/releasing mechanisms.

A dynamic transaction card with a display for providing barcodes is described. The barcodes can be generated by driving individual light emitting diodes (LEDs) of the display at frequencies of greater than 50 Hz. Due to the high frequency, the barcode can be readable by a barcode scanner, while remaining invisible to the human eye. The barcode can also be generated by driving a first set of LEDs at a different frequency and/or time interval than a second set of LEDs. Light waves from the first set of LEDs can constructively interfere with light waves from the second set of LEDs to create spatial voids readable by the barcode scanner.

A memory card and a terminal, where the memory card includes a storage device, a controller, and a memory card interface. The storage device and the controller are disposed inside a card body of the memory card. The memory card interface is disposed on the card body of the memory card. The controller is electrically coupled to the storage device and the memory card interface separately. Because a shape of the memory card is the same as that of a nano subscriber identity module (SIM) card, and a size of the memory card is the same as that of the nano SIM card, a nano SD card is provided.

An adaptable connector, a non-standard PCIe module, and a computer readable medium are disclosed. The adaptable connector for a PCIe interface allows for multiple standard PCIe modules and non-standard PCIe modules at different times An external I/O port has a set of non-PCIe I/O signal lanes coupled to the adaptable connector in lieu of a set of root port host PCIe signal lanes when a non-standard PCIe module is mated to the adaptable connector.
