Abstract: An operating method of a system-on-chip includes outputting a prefetch command in response to an update of mapping information on a first read target address, the update occurring in a first translation lookaside buffer storing first mapping information of a second address with respect to a first address, and storing, in response to the prefetch command, in a second translation lookaside buffer, second mapping information of a third address with respect to at least some second addresses of an address block including a second read target address.
