Abstract
An oscillation circuit, and a semiconductor device incorporating same, include: an oscillation unit with a plurality of inverters and configured to perform signal transmission between first and second nodes of the inverters such that each of the inverters performs an oscillation operation to generate clock signals having different phases when a control signal is activated, and latch a clock signal of the second node and cut off the signal transmission between the first and second nodes to stop the oscillation operations of the inverters when the control signal is deactivated; and a control unit to activate the control signal when an oscillation enable signal is activated, and deactivate the control signal using one of a clock signal output from an inverter connected to the second node and clock signals of which the phases lag that of a clock signal of the first node, when the oscillation enable signal is deactivated.
