Abstract

The present invention relates to a method of operating a memory system comprising a memory chip. An operating signal is generated at an operating frequency. The operating frequency is applied to the memory chip to control one or more electrical components of the memory system. A reference signal is generated at a reference frequency within the memory chip and a range of values for the operating frequency is detected based on the reference signal and the operating signal.
