Abstract:
A method in a clocked integrated circuit receiving an input clock signal having a clock frequency and a command signal for accessing a memory element in the clocked integrated circuit. The method detects the input clock signal having a clock frequency above or below a frequency threshold. The method generates a clock detect output signal having a first logical state in response to the clock frequency being below the frequency threshold and generates the clock detect output signal having a second logical state in response to the clock frequency being above the frequency threshold. The method delays the command signal by a first timing latency to generate a timing adjusted control signal where the first timing latency is one or more clock periods of the input clock signal. Finally, the method adjusts the first timing latency in response to the clock detect output signal.
