A universal serial bus (USB) controller and an execution method thereof are presented. The USB controller stores settings of different sensors in an external memory, or stores modified program codes when an originally stored program has bugs. With the execution of the set configurations, the program section to be execute is dynamically loaded into the random access memory (RAM) of the USB controller, so as to reduce the size of the RAM, thereby providing a large program modification space and avoiding the entire chip (the USB controller) from being stretched by an excessive large RAM.
