Abstract
Provided are an equalizer and a semiconductor memory device including the same. The equalizer includes a delay circuit and an inverting circuit. The delay circuit is configured to output, in response to a select signal, one of a delay signal delaying an input signal applied to an input/output node and an inverted signal inverting the input signal. The inverting circuit is configured to invert a signal provided from the delay circuit and output the inverted signal to the input/output node. The equalizer is configured such that when the delay circuit outputs the delay signal, the equalizer operates as an inductive bias circuit amplifying the input signal and outputting the amplified input signal, and when the delay circuit outputs the inverted signal, the equalizer operates as a latch circuit storing and outputting the input signal.
