Abstract
An electronic device comprises an interface unit, a control circuit and a microprocessor. The interface unit receives a first operational firmware from a host. The control circuit transfers the first operational firmware to a memory. The microprocessor executes the first operational firmware which stored in the memory. The microprocessor controls operations of the electronic device according to the first operational firmware. And the control circuit is electrically coupled to a non-volatile memory which stores a second operational firmware for performing a specific function also performed by the first operational firmware.
Claims9
An electronic device comprising:
- an interface unit for receiving a first operational firmware from a host;
- a control circuit for transferring the first operational firmware to a memory;
- and
- a microprocessor for executing the first operational firmware which stored in the memory;
