Abstract: PURPOSE: A data transmission circuit of a semiconductor device is provided which separates a data transmission line into a high potential transmission line and a low potential transmission line and transfers data in high speed by amplifying each of them with a skew logic, and outputs finally by sensing the transferred signal. CONSTITUTION: A data transmission circuit of a semiconductor device comprises: a high potential transmission line(HLINE) to transfer a high potential signal rapidly applied through a data transmission line(DLINE); a low potential transmission line(LLINE) to transfer a low potential signal rapidly applied through the data transmission line(DLINE); a first skew logic(21) transferring the high potential signal rapidly applied through the high potential transmission line(HLINE) after amplifying it; a second skew logic(22) amplifying and transferring the low potential signal rapidly applied through the low potential transmission line; and a sensing output part(30) sensing the high potential signal being output through the first skew logic and the low potential signal being output through the second skew logic and then finally outputting a rapidly transferred signal.
