Semiconductor device and method of driving the same

A semiconductor device comprising:

• a first clock control block suitable for generating a first control signal in response to a write training signal and a write-related information signal;
• a second clock control block suitable for generating a second control signal in response to a refresh signal and a precharge signal;
• a third clock control block suitable for generating a clock control signal by selecting one of the first and second control signals in response to the write-related information signal;
• and
• a data input block suitable for receiving a data signal for a write training mode in response to the clock control signal and a clock signal.

A method of driving a semiconductor device capable of entering a write training mode while entering a refresh mode, comprising:

• selecting one of a first control signal corresponding to the write training mode and a second control signal corresponding to the refresh mode by comparing write latency information with section information on a section ranging from when entering the write training mode to when the first control signal is generated;
• generating a clock control signal in response to the first control signal or the second control signal when entering the write training mode or the refresh mode;
• generating a limitation clock signal by defining a toggling section of a clock signal in response to the clock control signal;
• and
• receiving a data signal for the write training mode in response to the limitation clock signal.
