Abstract
A method for refreshing a dynamic random access memory DRAM and a computer system are provided. When an address of a refresh unit in a DRAM and refresh information of the refresh unit are acquired, the address of the refresh unit and the refresh information of the refresh unit are encapsulated as a DRAM access request, where the refresh unit is storage space on which one time of refresh is performed in the DRAM, and the refresh information of the refresh unit includes a refresh cycle of the refresh unit. Then, the address and the refresh information of the refresh unit are written into refresh data space using the DRAM access request, where the refresh data space is storage space that is preset in the DRAM and that is used for storing an address of at least one refresh unit and refresh information of the at least one refresh unit.
