Summary:The embodiments of the present disclosure provide a signal sampling circuit and a semiconductor memory device. The signal sampling circuit includes a signal input circuit, configured to determine a to-be-processed command signal and a to-be-processed chip select signal; a mode selection circuit, configured to determine a target mode clock signal and a target mode chip select signal according to the mode selection signal; a first clock processing circuit, configured to perform sampling and logic operation on the to-be-processed chip select signal and the target mode chip select signal according to the target mode clock signal, to obtain a first chip select clock signal; a second clock processing circuit, configured to perform sampling and logic operation on the to-be-processed chip select signal and the target mode chip select signal according to the target mode clock signal, to obtain a second chip select clock signal; and a command decoding circuit, configured to determine a target command signal.
