Abstract
A memory controller for controlling DRAM, comprising: a first storage unit configured to store requests that each comprise information about a priority and an access type received by the memory controller; a first control unit configured to select requests from the requests; a second storage unit configured to store the selected requests; and a second control unit configured to rearrange the requests stored in the second storage unit to generate a DRAM command and to issue the DRAM command to the DRAM, wherein the second control unit generates a priority access type indicating which access type request to preferentially issue to the DRAM, and the first control unit selects the requests, based on the information about the priority and the access type of each of the requests stored in the first storage unit, and the priority access type.
