Patent ID: 7868661

Claim:
A line driving circuit of a semiconductor device, the line driving circuit comprising: a driving unit reducing a full voltage swing width to output a signal to a first node, the driving unit comprising: a first NMOS transistor connected between a supply voltage and the first node; a second NMOS transistor connected between the first node and ground; and a differential amplification unit for generating first and second output signals to be applied to gates of the first and second NMOS transistors, respectively, wherein the first and second output signals have a complementary relationship, and the first and second output signals have a voltage level corresponding to a level of the supply voltage or a ground voltage, such that the first and second output signals have the full voltage swing width of the supply voltage to the ground, wherein the signal output by the driving unit has a reduced voltage swing width of a voltage level less than the supply voltage to the ground, a receiver having transistors connected to form a cross-coupled latch structure, the receiver receiving the signal outputted to the first node having the voltage swing width reduced by the driving unit, and the cross-coupled latch structure being configured to convert the signal back to a signal having the full voltage swing width, wherein the first node is connected to an Input node of an interior circuit in the semiconductor device by a transmission line.
