Semiconductor device and method for driving the same

A semiconductor device, comprising:

• a first voltage generation unit configured to generate a first voltage;
• a fuse unit coupled between an output node for receiving the first voltage and a fuse state sensing node;
• a driving unit configured to drive the fuse state sensing node with a second voltage in response to a rupture control signal;
• a voltage level control unit configured to generate a voltage level control signal in response to a detection enable signal and a fuse state sensing signal that corresponds to a voltage level of the fuse state sensing node;
• and
• a second voltage generation unit configured to increase and output a voltage level of the second voltage in response to the voltage level control signal.

A method for driving a semiconductor device, comprising:

• applying a first voltage and a second voltage to two ends of the fuse unit, respectively;
• detecting whether the fuse unit is ruptured or not;
• increasing a voltage level difference between the first voltage and the second voltage, when the fuse unit is not ruptured;
• and
• repeating the application of the first voltage and the second voltage, the rupture detection with the increased voltage level difference, and the voltage level difference increase sequentially until the fuse unit is ruptured.
