Abstract

Methods of operating a memory include determining a target voltage level for an access line voltage, determining a target overdrive voltage level for gating the access line voltage to an access line coupled to a plurality of memory cells, generating a voltage level for the access line voltage in response to its target voltage level and generating a voltage level for gating the access line voltage to the access line in response to the target overdrive voltage level, and applying the access line voltage to the access line while applying the voltage level for gating the access line voltage to a control gate of a string driver connected to the access line. Apparatus include a voltage regulator having variable resistance paths between a voltage signal node and an output node, and between the voltage signal node and an input of a comparator of the voltage regulator.
