Sense amplifier driver and semiconductor device comprising the same

A sense amplifier driver comprising N (natural number) inverters connected in a series, wherein an n−1th (n a natural number greater than 2) inverter among the N inverters comprises:

• a first pull-up transistor having a gate for receiving an input signal, a first electrode for receiving a control voltage determined by the amount of an off-current flowing through a plurality of transistors, and a second electrode connected to an output terminal of the n−1th inverter;
• and
• a first pull-down transistor having a gate for receiving the input signal, a first electrode connected to a ground voltage, and a second electrode connected to the output terminal of the n−1th inverter, and
• an nth inverter among the N inverters comprises:
• a second pull-up transistor having a gate connected to the output terminal of the n−1th inverter, a first electrode connected to a power voltage, and a second electrode connected to an output terminal of the nth inverter;
• a second pull-down transistor having a gate connected to the output terminal of the n−1th inverter, a first electrode, and a second electrode connected to the output terminal of the nth inverter;
• a first transistor having a gate connected to the first electrode of the first pull-up transistor, a first electrode connected to the ground voltage, and a second electrode connected to the first electrode of the second pull-down transistor;
• and
• a capacitor connected between the output terminal of the nth inverter and the ground voltage.
