Abstract
An amplifying circuit of a semiconductor integrated circuit includes a data amplifier that outputs an up-signal and a down-signal amplified according to a comparison result between an up-data signal and a down-data signal in response to a control signal. The data amplifier repeats an operation of amplifying the up-signal and the down-signal according to the comparison result between the up-signal and the down-signal to be fed back to the data amplifier.
