III- Sb charge-storage devices for non-volatile random access memories


What comes to you first when mentioning ‘memory’?

The pleasant time with best friends you cherish in brain or favorite videos/photos inside your digital devices? Well, both would be true, memory itself, it’s about the information stored somewhere. Of course, that’s why we use ‘memory’ to name similar stuff in your cellphone/tablet/laptop which does memorizing work as brain. Or, you could call it artificial memory to distinguish them from an traditional memory, just like artificial intelligence 😉 Alright, these two not much correlated…

RAM & Flash

Let’s focus on the latter one then, leave the brain memory research for experts in that area.

Nowadays, there’re two major memories on our laptop/PCs: RAM (random access memory) and flash, which usually found at memory and storage disk on your computer, respectively. Stepping a bit closer into memory, you’ll find couples of character of these two types ‘memory’. RAM is quick response but volatile, which indicates that, it will lose the information store inside when power off; flash work a bit slower than RAM but it could sustain the information stored inside even after power-off.

Non-volatile RAM

Here we go. As you see from headline, now we could have a talk about non-volatile random access memories.

Yes, I guess you’ve got it.
