Abstract
A buffering circuit of a semiconductor device includes: a first buffer configured to receive a first power voltage and a second power voltage as driving power voltages to buffer an input signal; a power supplier configured to adjust supply amounts of the first and second power voltages in response to a plurality of driving power signals to supply first and second driving power voltages; and a second buffer configured to receive the first and second driving power voltages, and to buffer an output signal of the first buffer.
