Countermeasure method for programming a non-defective plane of a non-volatile memory experiencing a neighbor plane disturb, comprising, once a first plane is determined to have completed programming of a current state but where not all planes have completed the programming, a loop count is incremented and a determination is made as to whether the loop count exceeds a threshold. If so, programming of the incomplete plane(s) is ceased and programming of the completed plane(s) is resumed by suspending the loop count and bit scan mode, and, on a next program pulse, applying a pre-determined rollback voltage to decrement a program voltage bias. The loop count and bit scan mode are resumed once a threshold voltage level equals a program voltage bias when the loop count was last incremented. BSPF criterion is applied for each programmed state. Advancement to the next loop only occurs if a programmed state is determined incomplete.
