Have you ever thought about how your beautifully designed smartphone storage works?
So many videos, pictures, applications are stored in one place. How is it possible to store so much data on your phone?
I’ll be explaining how the microchip stores data in your phone or SSDs on your computer.
The principle that works behind smartphone storage, is like an SSD in a PC.
Both use NAND technology. An SSD retains data in flash memory which is non-volatile and can be electrically erased and reprogrammed. If you see check the structure of an SSD, you see that the large black semiconductors on it. That stores all the data.
SSDs were used mainly in large mainframe systems but with the advancement of technology and faster read/write speed, commercially SSDs came into being after 1990. As compared to HDD, an SSD has 40 to 100 microseconds of access speed which is 100 times faster than an HDD.
It means that a program can run faster, decrease the page load time and help in providing better performance.
V-NAND technology claims to be the culprit here that holds data in your smartphone or SSDs. A smartphone stores pictures in RGB format which ranges from 0 to 255. Each of the numbers works in binary format which is 0 or 1. So, 3 colors and 8 bits multiply the pixel to 24 bits.
Now it calculates with the multiplication of the size of a picture which can consist of millions of bits.
If you zoom out a bit, you see that the memory cells are stacked vertically. This is the place where the Vertical NAND or NAND comes from.
This pile of memory cells, what is called a string is made out of 10 charge trap streak cells layered on top of another. At the point when data is composed to or from a string, just a single cell can be actuated at some random time, and to do that we utilize separate control doors joined to each layer in the string.
A similar sort of arrangement happens when charges are being added to a charge trap which is the way data is kept in touch with a memory cell. The primary concern is that just one layer in the string is either composed of or perused at some random time. How about we proceed in intricacy, next we copy this string multiple times, and this gets us a page of strings.
Also, to interface with the piece line selectors and control entryway selectors, some wires drop down from above and run opposite to the piece lines. Along these lines, how about we rapidly recap: 8 unique degrees of electrons are submitted on charge traps in request to store 3 pieces of data.
These charge trap streak memory cells are stacked into strings 10 cells tall, which are copied into pages of 32 strings in succession. Then, those pages of strings are copied until we have a square 6 lines profound, and here I am showing 2 squares. Doing some speedy increase we find that there are 3,840 memory cells equipped for putting away a sum of 11,520 pieces.
With every pixel in our image requiring 24 pieces, that implies that we can store 480 pixels or quite a bit of our general picture. That implies you need around 25 thousand times the size of this format to store the substance of this single picture. Isn’t it so interesting? All the principles work the same way as the above.
