Abstract
The level shifter circuit of an internal down converter includes a P channel MOS transistor constituting a resistance component, and a resistor constituting a resistance component. The temperature coefficient of resistance component is set larger than the temperature coefficient of resistance component so that the output voltage of level shifter circuit has a negative temperature characteristic. If a reference voltage generated by reference voltage generation circuit decreases when operating at a high temperature, the output voltage of level shifter circuit decreases as well. Thus, change in an internal voltage due to change in the operation temperature can be compensated.
