Provided is a semiconductor apparatus including a power management integrated circuit. The semiconductor apparatus includes an application processor and a voltage management integrated circuit. The application processor outputs clock information on an operation clock signal, and includes a core circuit. The voltage management integrated circuit receives the clock information from the application processor, and generates and outputs a core voltage having a voltage level corresponding to the clock information in response to the clock information. The operation clock signal is a clock signal, which has a variable frequency and is input to the core circuit of the application processor.
