Abstract:
1. A data transmission circuit comprising: a driving voltage generation unit configured to generate a driving voltage having a lower level than an external driving voltage; a switch unit configured to transmit the driving voltage when any one of a write enable signal and a read enable signal is enabled; a first transmission section configured to receive a data to drive a first global line to the driving voltage level, when the read enable signal is enabled, and receive a signal of the first global line to drive the data to a power supply voltage level, when the write enable signal is enabled; a second transmission section configured to receive the signal of the first global line to drive a second global line to the driving voltage level, when the read enable signal is enabled, and receive a signal of the second global line to drive the first global line to the driving voltage level, when the write enable signal is enabled; and a third transmission section configured to receive the signal of the second global line to drive a DQ pad to the power supply voltage level, when the read enabled signal is enabled, and receive the DQ pad signal to drive the second global line to the driving voltage level, when the write enable signal is enabled.
