Abstract
In a multi-supply-voltage semiconductor device including multiple blocks each of which has independent clock circuit, and operating with variable power supply, variable delay circuit which changes the amount of delay in accordance with the voltage value of the variable power supply is provided to a clock signal supplied to several blocks from clock generator circuit. This can reduce clock skew between the blocks even when the power supply voltage of variable power supply is changed.
