摘要： An ion barrier layer made from a dielectric material in contact with an electronically insulating layer is operative to prevent mobile ions transported into the electronically insulating layer from passing through the ion barrier layer and into adjacent layers during data operations on a non-volatile memory cell. A conductive oxide layer in contact with the electronically insulating layer is the source of the mobile ions. A programming data operation is operative to transport a portion of the mobile ions into the electronically insulating layer and an erase data operation is operative to transport the mobile ions back into the conductive oxide layer. When the portion is positioned in the electronically insulating layer the memory cell stores data as a programmed conductivity profile and when a substantial majority of the mobile ions are positioned in the conductive oxide layer the memory cell stores data as an erased conductivity profile.
