Abstract: A system on chip (SoC) includes a first core and a second core, first and second power gating switches, and a first power switch. The first power gating switch is arranged between the first core and a first power rail that receives a first voltage, and is selectively turned on in response to a first power gating signal. The second power gating switch is arranged between the second core and a second power rail that receives a second voltage, and is selectively turned on in response to a second power gating signal. The first power switch is arranged between the first power rail and the second power rail, and is selectively turned on in response to a first power control signal to connect the first power gating switch or the second power gating switch both the first power rail and the second power rail.
