摘要
A storage unit stores a memory access request to a DRAM. A deciding unit decides, based on a predetermined criteria, an issuance order of stored memory access requests. An issuance unit issues a command to the DRAM based on the decided issuance order. A determination unit, when the issuance unit issues a command of a first memory access request to the DRAM, selects, in accordance with the issuance order, a second memory access request that will next issue a command to the same bank as a bank where the first memory access request issues a command, and then determine whether the first and second memory access request target the same page. The issuance unit issues a command of the first memory access request without an auto precharge if determination unit determines that the same page is targeted.
