Data receiving circuit, data receiving system, and memory device

Abstract

The present disclosure provides a data receiving circuit, a data receiving system, and a memory device. The data receiving circuit includes: a receiving module, configured to receive a data signal and a reference signal, compare the data signal and the reference signal in response to a sampling clock signal, and output a first output signal and a second output signal; and a decision feedback equalization module, connected to a feedback node of the receiving module, and configured to perform a decision feedback equalization on the receiving module on the basis of a feedback signal to adjust the first output signal and the second output signal, wherein the feedback signal is obtained on the basis of data received previously, and an adjustment capability of the decision feedback equalization module to the first output signal and the second output signal is adjustable.
