Abstract
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.
Claims9
An input buffer of a semiconductor device, comprising:
- an input terminal configured to receive an external input signal;
- a first input buffer having an input coupled to the input terminal;
- and
- a second input buffer having an input coupled to the input terminal, where the first and the second input buffers are configured to transfer the external input signal,
- wherein the output of the second input buffer is blocked when the first input buffer transfers the received external input signal, and the output of the first input buffer is blocked when the second input buffer transfers the received external input signal.
An input buffer of a semiconductor device, comprising:
- an input terminal configured to receive an external input signal;
- a first input buffer having an input coupled to the input terminal;
- and
- a second input buffer having an input coupled to the input terminal, where the first and the second input buffers are configured to transfer the external input signal, a control signal generating circuit configured to receive the outputs of the first and second input buffers to generate a control signal to control the transfer paths of the first and the second input buffers;
- and
- a latch circuit configured to receive signals from the first and the second and input buffers to generate an internal operation signal of the semiconductor device.
