Design for stuff like nand includes a bunch of process steps that have a huge impact on the devices. NAND might require different equipment from what is already being used. It all requires intense calibration and many engineers with quite a lot of experience. Intel planned (don't know if they ended up doing it) to convert a plant built in 2010 to memory fabrication and it was going to cost 3.5 billion dollars and take years. It's not plug and play.
