| 摘要 |
An input buffer of the present invention has dual paths for increasing input signal processing speed by using two input buffers having input characteristics that differ from each other. The input buffer includes an input terminal receiving an external input signal; and first and second input buffers, both coupled to the input terminal for transferring an external input signal. The output signal of the second input buffer is blocked when the first input buffer transfers the external input signal, and the output signal of the first input buffer is blocked when the second input buffer transfers the external input signal.
