An in-depth 3D animated explanation of how solid-state drives and V-NAND flash memory store data using nanoscopic electrical charges.

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 solid-state drives, or SSDs in your computer, in tablets, and inside flash drives. The technology is called VNAND or V-NAND, and it's incredible how engineers were able to fit such an insane amount of memory storage capacity in such a small space.

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.

On “How is a bit saved in disk? What physics happen so that the 0 or 1 is stored?”

This is an excellent video about SSD storage link to this video This design is based on an electrical charge that is stored in a cell and can be changed and measured. The video goes into details of how cells are connected.
