Abstract
A refresh address counting circuit, a refresh address counting method, and a refresh address read-write circuit are provided. The refresh address counting circuit includes: a self-oscillation clock generation circuit, configured to generate, in each of refresh cycles, a self-oscillation clock signal based on at least one array activation signal upon acquiring a refresh signal; a self-oscillation mask circuit, configured to generate a self-oscillation mask signal under a preset refresh command; and a refresh address counter, configured to counting a refresh address based on the self-oscillation clock signal and the self-oscillation mask signal and to output a self-oscillation refresh address.
