Abstract:
A method of initializing a semiconductor device, wherein the semiconductor device stores initialization information in a serial electrically erasable and programmable read only memory (EEPROM) and includes a direct memory access (DMA), a serial EEPROM interface, and a register interface that are connected to a system bus according to the initialization information, the method comprising:(a) setting an operational channel to allow the DMA to automatically initialize the semiconductor device while in a reset state; (b) reading the initialization information from the serial EEPROM in response to the operational channel set in the DMA after the reset state of the semiconductor device is cancelled; (c) initializing the semiconductor device by writing the initialization information read from the serial EEPROM to the register interface; (d) generating an initialization completion signal for indicating that the initialization of the semiconductor device is completed; and (e) setting the register interface and the DMA in a state of normal operation following initialization of the semiconductor device.
