1. A method performed during programming of non-volatile storage, comprising:

  • boosting a group of unselected non-volatile storage elements,said group of unselected non-volatile storage elements includes a particular non-volatile storage element and a set of one or more non-volatile storage elements that have not completed full programming since a last erase process for said group, said group of unselected non-volatile storage elements further includes other non-volatile storage elements, said boosting includes applying one or more higher boosting signals to said set of one or more non-volatile storage elements and one or more different boosting signals to said other non-volatile storage elements, said one or more higher boosting signals are greater than said one or more different boosting signals; and
