Abstract
In a memory control apparatus for issuing a command for a bank corresponding to a transfer request, the transfer request for the corresponding bank is stored. The column address of the transfer request stored at the first is compared with the column addresses of a plurality of subsequent transfer requests. It is determined based on the comparison result whether to issue a command with precharge or a command without precharge for the transfer request stored at the first. The determined command is issued.
