1. A method for operation of a memory device, the method comprising:

  • biasing a common source to 0 volts;

    turning on a first source select gate coupled to a selected string of charge storage devices;

    turning off a second source select gate coupled to an unselected string of charge storage devices;

    turning on a source gate coupled to both the selected and unselected string of charge storage devices;

    biasing, with a read voltage, a selected access line coupled to a selected charge storage device in the selected string of charge storage devices;

    biasing a plurality of unselected access lines to a voltage greater than the read voltage, the unselected access lines coupled to charge storage devices not being read; and

    biasing a slot, coupled to a semiconductor well of the selected and unselected string of charge storage device, with 0 volts.
