Abstract
A semiconductor device is disclosed which can perform a stable data inputting operation by overdriving a terminal supplying an internal voltage used as a drive voltage for a write driver such that the internal voltage is maintained in a predetermined range irrespective of a continuous write operation. The semiconductor device includes an internal voltage generator which generates an internal voltage corresponding to a predetermined reference voltage, and outputs the generated internal voltage to an internal voltage supply terminal, an overdriver which overdrives the internal voltage supply terminal for a predetermined period of time in response to an enable state of a control signal, the control signal being enabled in a write operation, and a write driver which is enabled in response to the control signal, to drive data transferred via a global data bus line using a voltage supplied from the internal voltage supply terminal, and to output the driven data to a local data bus line.
