Classification: CPC G  H | IPC G  H

Claim 4:
5. The data sampling circuit of claim 1, wherein the sampling circuit comprises:
an input unit configured to sink current from an output bar node to a common source node in response to the input data;
an input bar unit configured to sink current from an output node to the common source node in response to data obtained by inverting the input data;
a first pull-up driving unit configured to pull up the output node in response to a voltage level of the output bar node;
a second pull-up driving unit configured to pull up the output bar node in response to a voltage level of the output node;
a first sinking unit configured to sink current from the common source node to a ground terminal; and
a second sinking unit activated when the speed control signal is deactivated and configured to sink current from the common source node to the ground terminal.
