Abstract:
Some aspects of the present disclosure a method. In this method, a wordline voltage is provided to a wordline, which is coupled to a plurality of memory cells. A boost enable signal is provided. The state of the boost enable signal is indicative of whether the wordline voltage at a predetermined position on the wordline has reached a non-zero, predetermined wordline voltage. The wordline voltage is selectively boosted to a boosted wordline voltage level based on the boost enable signal.
