    Abstract: A memory array device includes a stack of transistors over a semiconductor substrate, a first transistor of the stack being disposed over a second transistor of the stack. The first transistor includes a first memory film along a first word line and a first channel region along a source line and a bit line, the first memory film being disposed between the first channel region and the first word line. The second transistor includes a second memory film along a second word line and a second channel region along the source line and the bit line, the second memory film being disposed between the second channel region and the second word line. The memory array device includes a first via electrically connected to the first word line and a second via electrically connected to the second word line, the second staircase via and the first staircase via having different widths.

    Abstract: A 3D memory array has data storage structures provided at least in part by one or more vertical films that do not extend between vertically adjacent memory cells. The 3D memory array includes conductive strips and dielectric strips, alternately stacked over a substrate. The conductive strips may be laterally indented from the dielectric strips to form recesses. A data storage film may be disposed within these recesses. Any portion of the data storage film deposited outside the recesses may have been effectively removed, whereby the data storage film is essentially discontinuous from tier to tier within the 3D memory array. The data storage film within each tier may have upper and lower boundaries that are the same as those of a corresponding conductive strip. The data storage film may also be made discontinuous between horizontally adjacent memory cells.
