Abstract
A 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 clock receiving circuit, configured to receive an initial clock signal and perform frequency division processing on the initial clock signal to obtain a first clock signal; a sampling and logic circuit, configured to perform two-stage sampling processing and logic operation processing on the to-be-processed chip select signal according to the first clock signal to obtain a chip select clock signal, where the chip select clock signal includes two pulses, and the width of each pulse is a preset clock cycle; and a decoding circuit, configured to perform decoding processing and sampling processing on the to-be-processed command signal according to the to-be-processed chip select signal and the chip select clock signal to obtain a target command signal.
