An apparatus for reducing memory access conflict when a plurality of data processing elements perform simultaneous access to a memory including a plurality of pages, each of which includes a plurality of subpages, the apparatus comprising: an access arbiter mapping a subpage division address corresponding to least significant bits of a memory access address received from each of the data processing elements to another address having a same number of bits as the subpage division address in order for data to be output from each of the subpages in a corresponding page at a time of the simultaneous access; and a selector, prepared for each of the pages, selecting to output one of the data output from the subpages using the mapped results.
