Title:
SIGNAL SAMPLING CIRCUIT AND SEMICONDUCTOR MEMORY
Document Type and Number:
WIPO Patent Application WO/2023/178805
Kind Code:
A1
Abstract:
Embodiments of the present invention provide a signal sampling circuit and a semiconductor memory. The signal sampling circuit comprises: a signal input circuit, which is used for determining an instruction signal to be processed and a chip selection signal to be processed; a first instruction sampling circuit, which is used for performing, according to a first clock signal, two-stage sampling and logic operation processing on the chip selection signal to be processed to obtain a first chip selection clock signal; a second instruction sampling circuit, which is used for performing, according to the first clock signal, two-stage sampling and logic operation processing on the chip selection signal to be processed to obtain a second chip selection clock signal; and an instruction decoding circuit, which is used for performing, according to the chip selection signal to be processed and the first chip selection clock signal, decoding and sampling processing on the instruction signal to be processed to obtain a target instruction signal; or performing, according to the chip selection signal to be processed and the second chip selection clock signal, decoding and sampling processing on the instruction signal to be processed to obtain a target instruction signal.
