INTERNAL VOLTAGE GENERATION CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide an internal voltage generation circuit and a method capable of improving overshooting of an internal voltage level even if the level of an external power voltage rises in an overdriving operation. SOLUTION: This internal voltage generation circuit is composed of: a comparator for comparing a reference voltage with an internal voltage to output a first drive signal; an internal voltage drive part for outputting the internal voltage by responding to the first drive signal; an internal voltage sensing part for sensing the internal voltage to generate a second drive signal by responding to an active signal; and an overdriving control transistor for controlling the level of the first drive signal by responding to the second drive signal.
