A startup system using a boot code includes an external memory storing a boot code, a buffer connected to an external memory for storing the boot code transferred from the external memory, a DMA controller for commanding transfer of the boot code from the external memory to the buffer, and a mapping circuit connected to the buffer for mapping the boot code stored in the buffer onto a CPU. Accordingly, a flash ROM for storing the boot code may be eliminated, thereby reducing system cost.
