ABSTRACT:
A semiconductor device for improving an operation speed of a data input buffer includes: a plurality of data input buffers each for detecting a logic level of an input data by comparing the input data with a reference voltage to output the detected signal as an internal data signal; and a base voltage driving unit for driving a base power supply terminal of each data input buffer with one of a ground voltage and a negative boosted voltage according to an operation mode.
