    Abstract: A method of manufacturing a build-up printed circuit board, in which the circuit of a build-up printed circuit board including a core layer and an outer layer is realized by forming the metal seed layer of the core layer using a dry process, consisting of ion beam surface treatment and vacuum deposition, instead of a conventional wet process, including a wet surface roughening process and electroless plating. When the wet process is replaced with the dry process in the method of the invention, the circuit layer can be formed in an environmentally friendly manner, and as well, all circuit layers of the substrate including the core layer and the outer layer can be manufactured through a semi-additive process. Further, the peel strength between the resin substrate and the metal layer can be increased, thus realizing a highly reliable fine circuit.

    Abstract: The present invention relates to a sigma-delta analog-to-digital converter using a mixed mode integrator composed of an analog integrator and a digital integrator, which can prevent the performance degradation due to the saturation of an integrator of the overload of a quantizer. A sigma-delta analog-to-digital converter having an anti-aliasing filter, a sample and hold circuit, a sigma-delta modulator and a decimation filter comprises an overload estimating unit for judging the saturation or overload of an analog integrator; a mixed mode integrator which has the analog integrator and a digital integrator composed of a digital adder and a digital storing unit and integrates the output of the overload estimating unit in analog or digitally; and a quantization unit for converting the output of the mixed mode integrator to a digital signal.

    Abstract: Methods for multiple level program verify, memory devices, and memory systems are provided. In one such method, a series of programming pulses are applied to a memory cell to be programmed. A program verify pulse, at an initial program verify voltage, is applied to the memory cell after each programming pulse. The initial program verify voltage is a verify voltage that has been increased by a quick charge loss voltage. The quick charge loss voltage is subtracted from the initial program verify voltage after either a programming pulse has reached a certain reference voltage or a quantity of programming pulses has reached a pulse count threshold.

    Abstract: A lighting system which automatically assigns a unique address to each lighting device and controls each lighting device assigned the unique address is disclosed. The lighting system may include a plurality of lighting apparatuses, at least one bridge coupled to the plurality of lighting apparatuses, and a lighting controller coupled to the at least one bridge for controlling the lighting apparatuses. One of the at least one bridge or the controller may generate address data for assigning an address to one of the plurality of lighting apparatuses. The plurality of lighting apparatuses may include an LED module, a connection circuit configured to control a connection between the at least one bridge and the plurality of lighting apparatuses, and a controller configured to control the connection circuit based on the address.
