Abstract

See full text

A buffer includes an amplification circuit, an amplification current generation circuit, and a latch. The amplification circuit may change voltage levels of a first output node and a second output node based on a clock signal and a pair of input signals. The amplification current generation circuit may provide currents having different magnitudes to the first and second output nodes during a first operation period, and may provide currents having the same magnitude to the first and second output nodes during a second operation period. The latch circuit may latch the voltage levels of the first output node and the second output node based on the clock signal.
