Memory controller and memory control method

A memory control method executed by a memory controller that is formed to be able to issue a first write command for writing data of a predetermined length into a DRAM and a second write command for writing data which is less than the predetermined length in the DRAM, the memory controller including a storage unit configured to store a request to the DRAM, the method comprising:

• deciding an issuance order of a request stored in the storage unit;
• and
• issuing a DRAM command based on the decided issuance order,
• wherein in a period from the issuance of a preceding DRAM command until a second write command targeting the same bank as the preceding DRAM command is issued, if another DRAM command targeting a bank different from the bank targeted by the preceding DRAM command can be issued, the deciding comprises deciding the issuance order so that the other DRAM command that can be issued will be issued before the second write command.
