    • A circuit and a method for sampling a valid command by using an extended valid address window for high speed operation in a double pumped address scheme memory device are provided to easily assure the margin between with a decoded internal command signal to latch extended first and second internal address signals, by enabling the valid window of the extended first and second internal address signals to assure at least two periods of the valid window. A valid command signal generation part receives command signals in response to a clock signal and then generates a valid command signal. An address buffer sequentially receives first and second address signals in response to the clock signal and generates first and second internal address signals from the first and second address signals, and generates extended first and second internal address signals in response to the valid command signal. A command buffer generates internal command signals from command signals in response to the clock signal, and generates an internal clock signal by delaying the clock signal. An address latch circuit generates a decoded internal command signal by decoding the internal command signals in response to the internal clock signal, and latches and decodes the extended first and second internal address signals in response to the decoded internal command signal.

    • A semiconductor memory device comprising a pre-emphasis signal generator is provided to assure timing margin by efficiently removing noise due to the generation of reflection. A main output driver(10) outputs a data signal through an output stage. A subsidiary output driver(20) is connected to the output stage, and performs a pre-emphasis operation. A pre-emphasis signal generator(30) outputs at least one pre-emphasis signal to the subsidiary output driver in order to drive the subsidiary output driver. In the pre-emphasis signal generator, a first auto-pulse generator(31) generates a first auto-pulse in response to the transition of a first control signal. A first delay circuit(32) receives the first auto-pulse, and outputs a first pre-emphasis signal by delaying the first auto-pulse. A delay control part(35) controls the delay rate of the first delay circuit by applying a delay control signal to the first delay circuit.
