  • Image forming apparatus and network connection method thereof relates to an image forming apparatus which supports different network connections according to an operation mode
    Patent number: 8570562
    Abstract: An image forming apparatus includes a communication interface unit to communicate with a network using a physical layer protocol (PHY), a first control unit that includes a first Media Access Controller (MAC) to perform Media Access Control for the PHY when the image forming apparatus operates in a normal mode, and to control the image forming apparatus, a second control unit that includes a second Media Access Controller (MAC) to perform Media Access Control for the PHY when the image forming apparatus operates in a power saving mode, and a switching unit to switch a data path between the PHY, the first MAC, and the second MAC according to the operation mode of the image forming apparatus.

  • Method and apparatus to boot a system by monitoring an operating status of a NAND flash memory
    Publication number: 20060010282
    Abstract: A method and system to boot a system by monitoring an operating status of a NAND flash memory. The system includes a NAND flash memory to store a boot code used to boot the system, an internal memory to store the boot code transmitted from the NAND flash memory, a NAND flash memory controller to control the transmission of the boot code from the NAND flash memory to the internal memory, a CPU core to execute the boot code stored in the internal memory, and a signal monitor to monitor an operating status of the NAND flash memory to boot the system. The NAND flash memory controller holds operation of the CPU core until the boot code is stored in the internal memory. Even when the NAND flash memory cannot transmit the boot code properly due to an abnormal state, the boot code is executed using a separate external memory in order to reliably cope with the abnormal state of the NAND flash memory.
