Abstract
A dynamic random access memory (DRAM) unit and a data refreshing method thereof are provided. The DRAM unit includes a memory array, a refresh address module, and a refresh control module. The memory array includes multiple memory cells. The refresh address module produces a refresh word line address cyclically during a refresh mode. The refresh control module coupled to the memory array and the refresh address module obtains a start word line address and a stop word line address corresponding to the start word line address to form a memory word line address interval. Then, the refresh control module determines that the refresh word line address is within the memory word line address interval to execute a data charging operation to the memory cells corresponding to the refresh word line address, or stop the data charging operation otherwise, so as to reduce power consumption during the refresh mode.
