Abstract:
A frequency tuning apparatus may include an oscillator and a memory element connected to the oscillator. The memory element may have a variable resistance. An oscillation frequency of the oscillator may vary according to a resistance state of the memory element. The oscillator may be a ring oscillator. The memory element may be connected to an input terminal or a power terminal of the oscillator.
