How can a silicon chip store memory in flash drives?

Imagine putting your hand in mud so that it leaves an imprint. That's almost like what the chip does physically except you can reshape it back and put a different hand print.

Wow your ability to dumb that down is amazing, i didn't know how to explain that concept to someone.

ok what he was saying is that on a surface inside of the chip a writer like your computer will put an imprint on that surface. Flat is 0 and a hole is 1. That information is put in order to form binary code which uses 1s and 0s.

All I can tell you is this quote from I believe Arthur C. Clarke: "Any technology not understood is the equivalent of magic". Bottom line? I have no clue.

Consider this analogy: take 8 drinking glasses and line them up on your table. Because we are optimists, we will say that any glass that is more than 1/2 full is a ONE,and any glass that is less than 1/2 full is a ZERO. Because each glass has 2 'states' (1 and 0) and because there are 8 of them, I can use this to store 256 different combinations (in computer terms this is called a 'byte').

To read each bit, I stick my finger into the glass, and see if its half-full. Every time I do this, a little water sticks to my finger, so after many many 'reads' the value stored in the water can change. In Flash device, how ofter you can stick you finger in the glass is called the 'Endurance' of the flash (typically 1 million times) Note that the water in my glasses can also evaporate, so that after a long time my glasses are all empty. This is equivalent to a Flash property called 'Data Retention' -which can be 10s of years for typical flash devices.

This is pretty simplified, but I think you can get the idea.
