ABSTRACT:
A power gating structure controls a connection between a power supply terminal and a virtual power supply node so as to operate a logic circuit in a plurality of operation modes. The power gating structure includes a first path and a second path. In an active mode, the first path electrically couples the power supply terminal with the virtual power supply node in response to a first control signal. In a data retention mode, the second path electrically couples the power supply terminal with the virtual power supply node in response to the first control signal and a second control signal with a predetermined voltage level difference. In a power-down mode, both the first path and the second path electrically isolate the power supply terminal from the virtual power supply node in response to the first control signal and the second control signal.
