ABSTRACT:
The present invention discloses a duty ratio corrector which can reduce power consumption by blocking current paths between output terminals and a ground terminal by applying input signals for turning off switching devices for generating an auxiliary voltage for correcting a duty ratio at an initial stage, and which can improve an operational speed by changing the auxiliary voltage from a predetermined voltage, not 0V, to an target voltage, and a memory device having the same.
