Abstract: Disclosed herein is an apparatus for receiving data from memory. The apparatus receives a data signal and a clock signal output from memory and includes a Decision Feedback Equalizer (DFE) including two or more differential signal path units configured to determine and output an output value corresponding to the data signal. Each of the two or more differential signal path units may determine a current output value by reflecting a previous output value fed back from a different one of the two or more differential signal path units in such a way that they operate at different clocks, and may include an offset control unit configured to adjust an offset at an input stage and a feedback control unit configured to change a load of an output stage using the previous output value fed back from the different one of the two or more differential signal path units.

Abstract: Devices, systems and methods for fabricating semiconductor material devices by placing a batch of wafers in a chemical solution within a growth chamber. The wafers are held in a vertical direction and are actuated to move within the chemical solution while growing a layer over exposed surfaces of the wafers.

Abstract: A space weather monitoring system for polar routes includes: a satellite which flies over polar routes; a route-information providing server which receives data collected by the satellite monitoring the polar routes and generates various pieces of information about space weather; a flight vehicle which makes a request for information about the polar routes of the flight to the route-information providing server, and flies over the polar routes based on the received information; and a network which relays data among the satellite, the route-information providing server and the flight vehicle, so that an aurora-distribution map needed for an aircraft flight, an electromagnetic wave absorption map based on the ionosphere, information about space weather, and the situation and forecast of the space weather can be provided to an airline, thereby having effects on allowing the airline to check the information about the space weather in real time and fully considering a user who is unfamiliar to the space weather.
