Abstract
A temperature dependency of an internal clock signal generated by an internal clock generating circuit is effectively reduced. A temperature detecting circuit is provided to a variable clock generator for generating the internal clock signal and an oscillating cycle period of the variable clock generator is altered according to a detection signal of the temperature detecting circuit. A cycle of the internal clock signal is altered and a temperature dependency of the internal clock signal is effectively compensated for.
