Title:
REFRESH ADDRESS COUNTING CIRCUIT AND METHOD, REFRESH ADDRESS READ-WRITE CIRCUIT, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/020016
Kind Code:
A1
Abstract:
A refresh address counting circuit, a refresh address counting method, a refresh address read-write circuit, and an electronic device, which relate to the technical field of integrated circuits. The refresh address counting circuit comprises: a self-oscillation clock generation module, used for generating, within each refresh cycle, a self-oscillation clock signal according to an array activation signal after a refresh signal is obtained; a self-oscillation shielding module, used for generating a self-oscillation shielding signal under a preset refresh command; and a refresh address counting module, used for counting a refresh address according to the self-oscillation clock signal and the self-oscillation shielding signal and outputting a self-oscillation refresh address. Provided is a refresh address counting circuit suitable for DDR5.
