Abstract
Disclosed herein is an electronic device, including a plurality of row decoders. Each row decoder includes decoder logic generating an initial word line signal and word line driver circuitry generating an inverse word line signal at an intermediate node from the initial word line signal, and generating a word line signal at a word line node from the inverse word line signal. A word line underdrive p-channel transistor has a source coupled to the intermediate node, a drain coupled to a word line underdrive sink, and a gate controlled based upon the inverse word line signal. Negative bias generation circuitry generates the negative bias voltage at a gate of the word line underdrive p-channel transistor when the initial word line signal is at a logic high, and couples the gate of the word line underdrive p-channel transistor to ground when the initial word line signal is at a logic low.
