Abstract
A method and structure for passing a bitline voltage regardless of its voltage level via a bitline in a memory device is disclosed. In one embodiment, the method includes detecting the bitline voltage of the bitline, feeding a control signal at an activation voltage level to the bitline pass device to maintain a pass voltage differential of the bitline pass device when the bitline is selected and passing the bitline voltage via the bitline pass device in response to the control signal, where the pass voltage differential is greater than a threshold voltage of the bitline pass device regardless of a level of the bitline voltage.
