Semiconductor device including clock generation circuit for write write leveling operation and write operation

摘要

A semiconductor device includes: a clock generation circuit suitable for generating first and second write clocks that correspond respectively to a rising clock and a falling clock of an external clock during a write leveling operation, and for generating an input clock based on a delay of a write command by a delay time based on the rising clock during a write operation; a first transmission line suitable for transmitting the first write clock or the input clock as a first transmission clock; and a second transmission line suitable for transmitting the second write clock as a second transmission clock.
