Title:
REFRESH ADDRESS GENERATION CIRCUIT AND METHOD, AND MEMORY AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/231295
Kind Code:
A1
Abstract:
A refresh address generation circuit and method, and a memory and an electronic device. The refresh address generation circuit comprises a refresh control circuit (100) and an address generator (200), wherein the refresh control circuit (100) is used for sequentially receiving a plurality of first refresh instructions and respectively performing a first refresh operation, outputting a first clock signal when the number of first refresh operations is less than a preset quantity value, and outputting a second clock signal when the number of first refresh operations is equal to a preset quantity value n, wherein n is a positive integer greater than or equal to 1; the address generator (200) is coupled to the refresh control circuit (100), and pre-stores a first address and receives the first clock signal or the second clock signal; and during each first refresh operation, the address generator (200) outputs, in response to the first clock signal, a first address to be refreshed, wherein the first address to be refreshed comprises the first address, and the address generator (200) changes the first address in response to the second clock signal. The circuit can provide a refresh address for the same bank refresh.
