1. An apparatus, comprising:
a subword driver configured to drive a subword line, wherein the subword driver includes a transistor coupled to the subword line;
a word driver control circuit configured to provide a first control signal and a second control signal; and
a word driver configured to receive the first and second control signals, and based on the first control signal provide a driving signal including a plurality of reset pulses to the transistor of the subword driver to activate the transistor a corresponding plurality of times to discharge the subword line, and further provide the driving signal including a transition following the plurality of reset pulses to activate the transistor to further discharge the subword line.
