Ultra-Fast Random Bits: Magnetic Tunnel Junctions Explained #shorts

[00:00:00]The nice thing about it is that there are two things that are nice about it.

[00:00:04]One is that it's very fast. These entire dynamics happen on the order of a few nanoseconds. And so you can fairly easily get a new random bit from a single MTJ every, say, 5 to 10 nanoseconds or so.

[00:00:20]And these are very compact devices. You don't need a lot of circuitry in order to read out the state.

[00:00:26]And so if you then build small arrays of these magnetic tunnel junctions, you can get to very high throughput random bit generators in a fairly small area.
