How Does Flash Memory Work? (SSD)

In this video, I am going to explain how Flash Memory and Solid-state drives (SSD) work! Have fun, get some popcorn and enjoy!
Everybody stores pictures, music, and videos on their devices nowadays. The encoded information is even stored when the device shuts down due to low energy. After powering it on again, we find the same media and are glad that it did not disappear.
Flash memory was invented in 1984 by Japanese engineer Fujio Masuoka at the Toshiba Corporation. An electrical storage medium that does not require any energy to retain data. The name "Flash" was suggested by a coworker of Masuoka, Shoji Ariizumi because the erasure process of the newly invented device reminded him of a camera's flash. Later, the invention of flash memory allowed the wide use of solid-state-drives (SSD) that most of us have in their computers today.
The fundamental building block of flash memory is the floating-gate MOSFET, in short, FGMOS. Dependant on the kind of used technology, flash cells can store one or up to four bits (single-level cell (SLC) = 1 bit; multi-level cell (MLC) = 2 bits; triple-level cell (TLC) = 3 bits; quad-level cell (QLC) = 4 bits) - five bits per cell (penta-level-cell (PLC) = 5 bits) is in development currently. In a nutshell, these memory cells are arranged right next to each other and layered on top of one another to realize a highly capable storage medium. This makes it possible to produce a chip with trillions of flash cells, which then can store up to 1 TB of data! A perfect SSD! Flash memory is amazing and you know what? Engineers and semiconductor manufacturers will continue to shrink the size of flash cells in order to improve storage capacity and to reduce the price per bit. Therefore creating even better technology and cheaper solid-state-drives (SSDs) in the future!

We were born. Then we had to survive. Then some of us took conscious of their own existence and of its importance as whole, so they painted themselves. Then we recognized the importance and the necessity of living as groups, societies. Then we had to feed them. And because human is a very egocentric and egoistic specie, we had to split ressources according to merit. So we needed a way to keep track of each one's doing for and against the society and each other. Invention of writing. You can continue that little charade till the invention of computers. Everything is just a matter of need. And luck also. And need to understand too. Human is a specie made to go forward and to solve its own problems.

MLC is created not by more layers, rather variable voltage levels. MLC (2 bits per cell) simplistic cell data storage example: Voltage stored in cell 0v=00, 1v=01, 2v=10, 3v=11. It takes time and complexity to decode the voltages as well as write them and also there's a higher likelihood of errors due to the analog data hence error correction is needed.

Hello Nice Video, I have a question .At 2:52 you are saying that if there are no electrons at substrate then logic zero is assumed as electro are trapped at floating gate so no current will flow through substrate but why we are not measuring current ? without measuring current how shall we will come to know that there is a zero current. What is threshold voltage of flash cell ? what does it mean and suppose you apply voltage more than threshold voltage then what will happen ? Please reply. Thanks

It is said that NAND data can only be stored for two weeks at 55 degrees Celsius. If my SSD works at 55 degrees Celsius, does it mean that the controller needs to rewrite the data after every two weeks of operation to prevent data loss? Or rather, after powered on, NAND itself could prevent electronic loss without consuming the lifespan？
