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 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.

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.

МАЛО КТО ЗНАЕТ О СУЩЕСТВОВАНИИ ЭТИХ МЕСТ. 9 САМЫХ КРАСИВЫХ ЯВЛЕНИЙ ПРИРОДЫ
В мире есть два типа людей — те, кто в путешествиях предпочитает нежиться на пляже, и те, кто ещё за несколько месяцев до отъезда составляет себе грандиозный список всего, что нужно посмотреть. Выставки, исторические здания, архитектурные ансамбли… Всё это завораживает и притягивает нас, но по своему масштабу и красоте редко может сравниться с местами, созданными самой природой. Сегодня мы расскажем вам о девяти невероятных локациях, которые стоят того, чтобы отправиться ради них хоть на край света.
