Abstract
A method of measuring a frequency of an input clock signal may include generating an output pulse responsive to an edge of the input clock signal, and charging an electrical circuit responsive to the output pulse. An analog output signal may be generated responsive to the charged electrical circuit, and the analog output signal may be converted into a digital value representing a frequency of the input clock signal. Related frequency measuring circuits and memory devices are also discussed.
