Does an USB stick gain weight when you put files on it? or to put it a different way: Are electrons from outside used to store data on an USB stick?
Since I'm quite new to electronics I cannot give a logical explanation. I searched a lot on the web and I found the folowing data:
? Flash memory uses the Fowler?Nordheim tunneling principle to charge a thin oxide layer ? Excited electrons are pushed through and trapped on other side of a thin oxide layer, giving it a negative charge ? The negative charge give the floating-gate transistor a value of '1' or '0'
Although I can imagine how the principle works, I do not fully understand the exact technics.
USB sticks need power supply to read and alter the data on it. But when information is added, has the amount of electrons increased?
Consider the stick is fully empty at the beginning (all transistors are not negatively charged and thus have the status of '1')
