摘要： A system-on-chip and an electronic device including the system-on-chip are provided. The system-on-chip includes a power switch, a logic block, a memory device, and a buffer. The power switch is coupled between a first power supply line and a virtual power supply line, and turns on in response to a switch control signal. The logic block is coupled between the virtual power supply line and a ground line. The memory device is coupled between a second power supply line and the ground line. The buffer is coupled between the second power supply line and the ground line, and generates the switch control signal based on a sleep signal.

摘要： In one embodiment, the voltage droop monitoring circuit includes a ring oscillator circuit block configured to generate a plurality of oscillation signals and configured to output a selected oscillation signal from one of the plurality of oscillation signals based on a first control signal. The first control signal is based on a power supply voltage of a functional circuit block. The voltage droop monitoring circuit further includes a counter configured to generate a count value based on the selected oscillation signal, and a droop detector configured detect droop in the power supply voltage of the functional circuit block based on the count value and at least one threshold value.
