How do SSDs Work? | How does your Smartphone store data? | Insanely Complex Nanoscopic Structures!
Have you ever wondered how your smartphone can store countless pictures, songs, or videos? Or, have you wondered when you download a podcast to your smartphone, where does it actually get stored? In this video, we will open up your smartphone and take a look at the inside of the memory storage microchip. This same microchip is also used to store data in solidstate drives, or SSDs in your computer, in tablets, and inside flash drives. The technology is called VNAND or VNAND, and it's incredible how engineers were able to fit such an insane amount of memory storage capacity in such a small space.

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) How charge trap flash works. (details on a single memory cell) 4) How strings of memory cells work (details on a stack of memory cells) 5) How a massive array of memory cells are organized. (Terabit Cell Array Transistor, TCAT) 6) How is VNAND manufactured? 7) Possible episode on an analogy using a city & apartments to explain VNAND.
