Abstract
A memory access control device of an embodiment includes a data memory configured to record information of an access request relating to reading and writing of data to a main memory, and a controller configured to receive notification of the access request and select an access destination with reference to recording content of the data memory. When history of a request for write access and history of a request for read access to an address designated by the access request are recorded in the data memory, the controller selects a cache memory as the access destination, and otherwise, selects the main memory as the access destination.
