It's a puzzle as to how your smartphone or the solid-state drive in your laptop can store gigabytes to terabytes of data by the click of a button! It's amazing that your devices work flawlessly, and the information doesn't leak out. In this video, we'll learn how scientists and engineers use quantum mechanics to store this information reliably. We'll take a look on the inside of the 3D NAND technology, and see an application of quantum mechanics- specifically quantum tunneling.

This video is part of a series that intends to thoroughly explain how SSDs, and more specifically how VNAND works. These are the episodes in the series:
1) [18min] Overview on how SSDs / VNAND / Smartphone storage works.
2) [3min] Quick/Abridged episode of the overview
3) [7.5min] Writing to a memory cell using Quantum Mechanics
4) Reading from a charge trap flash memory cell.
5) How strings of memory cells work (details on a stack of memory cells)
6) How a massive array of memory cells are organized. (Terabit Cell Array Transistor, TCAT)
7) SSD Architecture
8) How is VNAND manufactured?
