A DMA controlling method comprises the steps of: building a linking table, wherein the linking table records the status of each memory block and of a pointer pointing to a next memory block; activating a first memory block; receiving an interrupt signal and linking to a next associated memory block after the first memory block finishes a data transfer; activating the next associated block; and updating the linking table to release the first memory block for reuse.
