Abstract
A master issues an access request to the memory. The memory controller receives the access request via a bus. An access control unit controls an output of the access request issued by the master to the memory controller by the granting an access right. The access control unit manages a number of grantable rights indicating a number to which the access rights can be granted based on a weight of 0 or more and less than 1 according to a probability that the granted access right is used, and grants the access right within a range of the number of grantable rights.
