Abstract
A semiconductor apparatus includes a power gating control circuit and a power gating circuit. The power gating control circuit generates a power gating signal based on an idle signal, a clock synchronization signal, and a delayed idle signal. The power gating circuit applies at least a first operating voltage to an internal circuit based on the power gating signal.
Claims8
A semiconductor apparatus comprising:
- a power gating control circuit configured to change a voltage level of a common node based on a clock synchronization signal and an idle signal, configured to latch the voltage level of the common node to generate a power gating signal, and configured to prevent the power gating signal from being enabled when the idle signal is enabled;
- and
- a power gating circuit configured to apply a first operating voltage to an internal circuit of the semiconductor apparatus responsive the power gating signal.
