When it gets too hard to put more transistors on a surface, semiconductor engineers started layering up and moved to 3D technologies. Is 3D NAND a reliable solution with unlimited numbers of layers? And how does the technology extend the lifespan of Moore’s Law? Let’s hear from Jim Handy of Objective Analysis about 3D NAND, from its technical challenges to future development. Handy is founder and general director at Objective Analysis. He’s a respected semiconductor industry analyst, and also well known for his blogs (The Memory Guy and The SSD Guy).
