Abstract

A method of programming a memory system by selectively applying a program voltage to a selected wordline connected to a memory transistor to be programmed. A first bias voltage is applied to a first wordline adjacent to the source side of the selected wordline. The first bias voltage is also applied to a second wordline adjacent to the drain side of the selected wordline. A second bias voltage is applied to a third wordline adjacent to the drain side of the second wordline. A third bias voltage is applied to a fourth wordline adjacent to the source side of the first wordline. A pass voltage is also applied to the remaining wordlines that do not have one of a bias voltage and a program voltage applied, the pass voltage a selected voltage level.
