How do USB Flash Drives store information?
In: Technology
Basically every cool thing is built around transistors which are little electronic switches
Your Flash drive has a chip with billions of these little switches
When we go to store data we ram electrons into the gate of these little switches which gets them stuck in an on or off state. The little electrons are trapped in an insulator and can’t go anywhere when power is removed
When you go to read your file back, the controller goes through and checks the state of the switches, on is 1 and off is 0, and then it reports all those bits to your computer.
We’ve made denser ones by having switches that we can turn kinda on to store more than one bit per switch and then check how on the switch is when you read from it
