System-on-chip including a power path controller and electronic device

A system on chip (SoC) includes a plurality of function circuits including a plurality of logic circuits and a plurality of function circuits each of which includes a logic circuit and a memory, and a plurality of power path controllers respectively coupled to a plurality of first power sources at first input terminals, commonly coupled to a second power source at second input terminals, and respectively coupled to the memories at output terminals. The logic circuits are respectively coupled to the first power sources, and configured to be supplied with a plurality of first power supply voltages from the first power sources, respectively. Each of the memories is configured to be selectively supplied, by a corresponding one of the power path controllers, with one of a corresponding one of the first power supply voltages from a corresponding one of the first power sources and a second power supply voltage from the second power source.
