A data transmission circuit of a semiconductor integrated circuit capable of achieving high integration and high-speed operation is disclosed. A data input/output line is constructed as a pair of common input/output lines 71 and 72, and input transistors 77 and 78 are constructed as a pair. The potential of the bit lines are not transferred to the input/output lines 71 and 72 through the channels of output transistors 75 and 76, but transferred to control terminals of the output transistors 75 and 76 coupled to the input/output lines 71 and 72, to thus access predetermined data through the sensing operation of the output transistors 75 and 76. Therefore, the data input/output can be performed at high speed, and its construction is compact, thereby improving the degree of integration of a semiconductor integrated circuit.
