3D NAND – Samsung’s Path to 1XXX-Layer

Discover Samsung's 236-Layer 3D NAND and learn why the through-type cell metal contact in the upcoming 286-Layer V9 is key to the future of 3D NAND.

Samsung eight-generation (V8) 236-Layer 3D NAND flash memory had been analyzed. While that is happening, Samsung had begun ninth-generation (V9) 286L-Layer 3D NAND flash memory. A key feature of V9 is the through-type cell metal contact (commonly known as word line contact). Why is it needed, and what changes are expected, on the path to a thousand layers?
