摘要： 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.

摘要： A programmable memory device includes a plurality of one-time programmable (OTP) memory units, a search unit, a writing unit, and a reading unit. Each OTP memory unit is assigned an address. The search unit searches for the first writable OTP memory unit from the plurality of OTP memory units in a writing operation, or searches for the last programmed OTP memory unit from the plurality of OTP memory units in a reading operation. The writing unit writes data to be written and the bit length of the data to the first writable OTP memory unit. The reading unit sequentially reads data from the last programmed OTP memory unit.
