Magnetoresistive RAM
Magnetoresistive RAM, or MRAM for short, is a special kind of computer memory that uses tiny magnets to store information. Imagine having a big box filled with lots of tiny toys, like little cars and toy animals. Each toy has a special place where it can be put, kind of like a parking spot. In MRAM, these special parking spots are made of two tiny magnets that stick together, like two really strong magnets that you've played with before.
When you want to store a piece of information in MRAM, the computer sends a little electrical current through these magnets, which makes them either stick together or pull apart. If they stick together, that means the information is a "0," and if they pull apart, that means the information is a "1." It's like a very fancy game of "Magnetic Tic-Tac-Toe," and the computer keeps track of which magnets are stuck together and which ones aren't.
When you need to access that information later, the computer can just read the magnets and see which ones are stuck together and which ones aren't. That way, it can figure out what information was stored there earlier.
MRAM is really special because it's very fast and uses very little energy. That means it's really good for things like cell phones and other gadgets that need to work quickly and efficiently. Plus, it can remember information even when the power is turned off, just like how you can remember your favorite toy even when you aren't playing with it.
