Abstract:
1. A semiconductor device comprising: an internal voltage input buffer configured to determine voltage levels of a pull-up driving node and a pull-down driving node as a result of a comparison between a voltage level of an internal voltage node and a voltage level of a reference voltage node such that the pull-up driving node and the pull-down driving node to maintain a voltage level difference; an internal voltage driving block configured to pull-up drive the internal voltage node in response to the voltage level of the pull-up driving node and pull-down drive the internal voltage node in response to the voltage level of the pull-down driving node; and a current sourcing block connected to the pull-up driving node in a current mirror type with respect to the internal voltage driving block and configured to provide a source current to the internal voltage node, wherein an amount of current provided by the current sourcing block is N times (N is an integer greater than 1) larger than an amount of current provided to the internal voltage node by the internal voltage driving block.
