Abstract
The present disclosure provides a method for controlling bit line voltages in a three-dimensional memory device. The method includes ramping up a bit line clamp regulation voltage and a control signal regulation voltage. The method also includes ramping up a bit line clamp enabling voltage and a control signal enabling voltage. The method also includes increasing a bit line clamp voltage in one stage, and increasing a control signal voltage in two stages. The method also includes decreasing the control signal voltage. The method also includes ramping down the bit line clamp enabling voltage, the bit line clamp regulation voltage, the control signal enabling voltage, and the control signal regulation voltage. The method further includes decreasing the bit line clamp voltage.
