摘要：
A circuit for controlling a sense amplifier over-driving voltage includes a comparator for comparing an internal voltage and an over-driving voltage and a pumping circuit based on a sense amplifier circuit using an internal voltage and an over-driving voltage, so that it is possible to prevent an over-driving when a sense amplifier is operated by a low voltage when an external power voltage is decreased, and the over-driving voltage becomes identical with the internal voltage or lower than the same.
