ABSTRACT:
There is provided a data acceleration device comprising a pull-up driver for driving a pull-up in response to the signal level on a first node, a pull-down driver for driving a pull-down in response to the signal level on the first node, a first pull-up circuit for pull-up driving a second node which is electrically coupled with the first node, in response to an output signal from the pull-up driver, a first pull-down circuit for pull-down driving the second node, in response to an output signal from the pull-down driver, a delay circuit for delaying a signal from the second node by a preset time to output a delayed signal, a first switch for switching an operation of the first pull-up circuit in response to an output signal from the delay circuit, and a second switch for switching an operation of the first pull-down circuit in response to the output signal from the delay circuit. Also, there is presented a data transmission apparatus including the data acceleration device.
