摘要： A system on chip (SoC) including a memory management unit (MMU) and a memory address translation method thereof are provided. The SoC includes a master intellectual property (IP) configured to output a request corresponding to each of a plurality of working sets; an MMU module comprising a plurality of MMUs, each of which is allocated for one of the working sets and translates virtual addresses corresponding to the request into physical addresses; a first bus interconnect configured to connect the MMU module with a memory device and to transmit the request, on which address translation has been performed in at least one of the MMUs, to the memory device; and a second bus interconnect configured to connect the master IP with the MMU module and to allocate one of the MMUs for each of the working sets.
