  • Publication number: 20240064984
    Abstract: A 3D memory array includes a row of stacks, each stack having alternating gate strips and dielectric strips. Dielectric plugs are disposed between the stacks and define cell areas. A data storage film and a channel film are disposed adjacent the stacks on the sides of the cell areas. The middles of the cell areas are filled with an intracell dielectric. Source lines and drain lines form vias through the intracell dielectric. The source lines and the drain lines are each provided with a bulge toward the interior of the cell area. The bulges increase the areas of the source line and the drain line without reducing the channel lengths. In some of these teachings, the areas of the source lines and the drain lines are increased by restricting the data storage film or the channel layer to the sides of the cell areas adjacent the stacks.
