RESISTANCE CIRCUIT FOR TERMINATION

摘要

PURPOSE: A resistance circuit for termination is provided to have the range of the high resistance value and the high resolution in 'the state which the area of the circuit increases. CONSTITUTION: If the calibration code has the set value, the control signal generating part(610) generates 'the control signal in which the logical value changes. A plurality of parallel resistance(620) is turned on/off in response to the calibration code. The resistance value change mean(630) changes the overall resistance value of the termination resistance circuit in response to the control signal.
