Abstract
A memory controller, on receiving a write request to write write-data into an address of a second memory region issued by a processor, determines whether read-data requested to be read from an address of a first memory region by the processor is matched with the write-data requested to be written into the address of the second memory region, and if the read-data is matched with the write-data, prevents the write-data from being written into the address of the second memory region.
