An SoC(System on Chip) system for a multimedia system is provided to offer the quick control without influencing the data transmission through the efficient application of a bus structure and switch structure. An SoC comprises a processor(100), a plurality of peripheral devices(130), a plurality of memories(180), a control bus(120), a data bus(190), a bridge, a plurality of memory controllers(150), a DMA(Direct Memory Access) controller(140) and A matrix switch(170). The memory controllers control each of memories. The DMA controller controls the data transceiving between the peripheral devices and memories. The matrix switch is connected between the DMA controller and memory controllers to offer the simultaneous multiple memory access.
