Abstract:
Apparatuses and methods for controlling the discharge of subword lines are described. The rate of discharge and/or the voltage level discharged to may be controlled. In some embodiments, a main word line may be driven to multiple low potentials to control a discharge of a subword line. In some embodiments, a first word driver line signal and/or a second word driver line signal may be reset to control a discharge of a subword line. In some embodiments, a combination of driving the main word line and the first word driver line signal and/or the second word driver line signal resetting may be used to control a discharge of the subword line.
