  • Publication number: 20080162790
    Abstract: A NAND flash memory in which a command/address pin is separated from a data input/output pin. The NAND flash memory includes a memory cell array used for storing data, a command/address pin through which a command and an address are received for transmitting data in the memory cell array, and a data input/output pin through which data are transmitted in the memory cell array. The command/address pin is separated from the data input/output pin in the NAND flash memory. Data input/output speed is increased. Furthermore, the NAND flash memory can perform a bank interleaving operation with a minimal delay time.

  • Publication number: 20080109600
    Abstract: An optical disk drive includes a non-volatile memory. The optical disk drive is booted based on driving information stored in the non-volatile memory. When a write command is received from a host, the optical disk drive stores data to be recorded in an optical medium in the non-volatile memory and then writes the data in the optical medium independent of the host.

  • Patent number: 7332896
    Abstract: An apparatus and method for controlling a supply voltage of a multiple interface card includes a first voltage adjustment unit, a second voltage adjustment unit, an internal circuit, a first voltage controller, and a second voltage controller. The first voltage controller adjusts a first supply voltage to a first internal supply voltage used as an operating voltage of the internal circuit and supplies the first internal supply voltage to the internal circuit. The second voltage adjustment unit adjusts a second supply voltage to a second internal supply voltage used as an operating voltage of the internal circuit and supplies the second internal supply voltage to the internal circuit. The first voltage controller detects the first supply voltage and, according to the first supply voltage, either applies the first supply voltage to the first voltage adjustment unit or blocks the first supply voltage from the first voltage adjustment unit.

  • Publication number: 20060043202
    Abstract: A multi-interface card includes smart card interface, memory card interface, card controller and memory module. The smart card interface interfaces with a smart card host using a smart card protocol. The memory card interface interfaces with a memory card host using a memory card protocol. The card controller controls the smart card host and memory card host so that the smart card host and the memory card host simultaneously interface with the smart card and the memory card interfaces, respectively. The memory module stores data transferred from the smart card host and memory card host. The multi-interface card simultaneously supports the smart card interface and the memory card interface. Thus, the one multi-interface card can support a subscriber authentication function and a data storage function.

  • Publication number: 20060025075
    Abstract: The present invention provides a system with a plurality of Bluetooth dongles connected to a single host. Each dongle is connected to a different port on the host and each dongle can accommodate a piconet of up to seven Bluetooth devices. The host communicates with the Bluetooth devices via Bluetooth channels. The host includes an application layer, a Host Control Interface (HCI) layer and an interface device driver layer. An Interface Map Table (IMT) is stored in the host. The IMT associates each port on the host with the BD address of a particular Bluetooth dongle and with the channels associated with the particular dongle. The HCI layer and the Interface handler layer consult the IMT to direct commands and data to the correct port on the host.
