摘要： A semiconductor integrated circuit is capable of accurately detecting the characteristics of a chip. The semiconductor integrated circuit includes a monitor circuit and a control circuit. The control circuit generates a clock pulse signal having M successive pulses (M is 2 or a greater integer), and outputs the clock pulse signal to the monitor circuit. The monitor circuit includes a frequency divider and a ring oscillator. The frequency divider frequency divides the clock pulse signal by M and generates the resulting signal as an enable signal. The ring oscillator generates an oscillation signal as a monitor output value during a period defined in accordance with the enable signal.

摘要： When an operation of a specified one of monitor circuits is defective or any of elements forming a ring oscillator in each of the monitor circuits has characteristic abnormality, if voltage control is performed based on a result from the monitor operating at a lowest speed, a required voltage may be overestimated. This results in an increase in power consumption, and also causes an accuracy reduction when the average value of detection results from the multiple monitors is calculated. The multiple monitor circuits are provided. Of the detection results therefrom, any detection result falling outside a predetermined range is ignored, and the average value of the remaining monitor results is used as a final monitor detection value.
