Data transmission circuit and operation method thereof

An operation method of a data transmission circuit, comprising:

• receiving a plurality of input data signals respectively through a plurality of data transmission lines;
• detecting data pattern information of an adjacent data signal corresponding to a victim data signal among the plurality of input data signals;
• controlling a reference voltage level to be reflected into the victim data signal on the basis of the data pattern information;
• and
• outputting an output data signal on the basis of the victim data signal into which the controlled reference voltage level is reflected.

An operating method of a data transmission circuit, the method comprising:

• raising a reference voltage level to be compared with a victim data signal according to one of rising and falling edges of at least one adjacent data signal;
• and
• lowering the reference voltage level according to the other one of the rising and falling edges of the at least one adjacent data signal,
• wherein the victim data signal and adjacent data signal are transmitted by data signal lines adjacent to each other.
