Abstract:
A data transmission device comprising:a data bus sense amp controlled according to a control signal which is a pulse signal, for detecting and amplifying a data applied to a data bus; a plurality of driving units for buffering and outputting an output from the data bus sense amp; a read data line for receiving a pulse data transmitted by the plurality of driving units; a plurality of pull-down units controlled according to an output signal from the plurality of driving units, for performing a pull-down operation on the read data line; a plurality of multi-delay units controlled according to a detection signal detecting a period of an externally-inputted clock signal, for delaying the pulse data applied to the read data line for a different delay time; and a pull-up unit controlled according to an output signal from the plurality of multi-delay units, for resetting the data line.
