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!
