Abstract
A clock generating circuit includes an oscillator, a clock counter, a finite state machine, and a non-volatile memory. The oscillator outputs an oscillator clock signal having a period based on a trim value. The clock counter counts the oscillator clock signal for a reference time. The finite state machine obtains the count value of the counted oscillator clock signal from the clock counter, and in a test mode, compares the count value with a target count value and changes the trim value based on the comparison result and determines a final trim value based on the changed trim value. The non-volatile memory stores the final trim value that is determined.
