Abstract
A memory control circuit includes an access storage unit configured to store access requests for a memory, a status management unit configured to, based on the access requests stored in the access storage unit, perform priority access type switching between two access types obtained by classifying the access requests, and an access selection unit configured to select and execute an access request stored in the storage unit. The access selection unit performs, if the priority access type switching is in progress and there is time for executing an access request of a priority access type before the priority access type switching, selecting the access request of the priority access type before the priority access type switching, and if the priority access type switching is not in progress, selecting an access request of the priority access type.
