Abstract
Systems, apparatuses and methods may provide for technology that includes a charge pump and applies a program voltage from the charge pump to selected wordlines in the NAND memory. The technology may also conduct a discharge of the program voltage from the charge pump and maintain a connection between the selected wordlines and a pass voltage of the charge pump while the program voltage is being discharged. In one example, the connection between the selected wordlines and the pass voltage prevents the selected wordlines from floating.
