Correct me if I'm wrong but isn't copper interconnect important to accomplish faster speed grades? At what point will other DRAM guys have to replace aluminum with copper? I don't know much about copper use in the DRAM industry. What I know comes from here: techonline.com "The potential benefits of copper for DRAM are fairly straightforward. Because of its lower resistivity compared with aluminum, it can be used in the cell array to shrink the height of the minimum pitch metal lines, easing the problem of dielectric gap fill and decreasing the parasitic bitline-to-bitline capacitance and noise coupling. In the periphery, copper allows longer wiring runs and can support new, high-speed DRAM architectures such as DDR3 or DDR4."
