| 1. A global signal driving device, comprising:
a driving control unit configured to generate a plurality of driving control signals based on a bank address;
a driving unit including a plurality of driving sectors to adjust a driving strength of the driving unit in response to the
driving control signals, thereby selectively driving the global signal to a plurality of banks, wherein the driving strength
is adjusted by activating one or more driving sectors in response to the driving control signals; and
wherein the driving control unit generates the driving control signals differently according to a transmission load of a global
signal line through which the global signal is transferred to the banks.
