Abstract
Provided is an internal power supply voltage generation circuit, with which a through current that flows during the operation of a logic circuit can be prevented from being excessive due to fluctuations in threshold voltage of a P-type transistor and an N-type transistor forming the logic circuit, and current consumption can be suppressed. Provided is an internal power supply voltage generation circuit for generating an internal power supply voltage at an internal power supply terminal and supplying the internal power supply voltage to a logic circuit, the internal power supply voltage generation circuit including a transistor having a source follower configuration for outputting a voltage applied to a gate thereof. A value of the internal power supply voltage is given based on the sum of an absolute value of a threshold voltage of an N-type transistor and an absolute value of a threshold voltage of a P-type transistor.
