Abstract
A semiconductor device includes a buffer unit configured to include first and second buffers, connected to each other in a cross-coupled manner, to receive a reference voltage and to buffer an input signal applied to the first and second buffers based on the reference voltage to drive an output terminal with a current-driving capacity; and a drive power adjustor configured to adjust the current-driving capacity depending on a level of a power supply voltage applied to the buffering unit.

A semiconductor device, comprising:
- a buffer unit configured to include first and second buffers, connected to each other in a cross-coupled manner, to receive a reference voltage and to buffer an input signal applied to the first and second buffers based on the reference voltage to drive an output terminal with a current-driving capacity;
- and
- a drive power adjustor configured to adjust the current-driving capacity depending on a level of a power supply voltage applied to the buffering unit.
A semiconductor device, comprising:
- a buffer unit configured to include first and second buffers, connected to each other in a cross-coupled manner, to receive a reference voltage and to buffer an input signal applied to the first and second buffers based on the reference voltage to drive an output terminal with a pull-up/pull-down current-driving capacity;
- and
- a supplementary drive unit configured to drive the output terminal by a supplementary pull-up/pull-down current-driving capacity depending on a level of a power supply voltage applied to the buffering unit.
