This New Kind of Memory Could Make RAM And ROM Obsolete

Like salt and pepper, Like peanut butter and jelly, like milk and butter milk, they are seem like perfect couple you love (Hate eachother) the two similar type of computer memory truly complete one other
ROM (Read Only Memory) and RAM (Random Access memory) lets run together on those computer

In past, we need ROM & RAM but now , using third party of computer memory is on the scene and it’s capable doing everything on it’s own plus a little more.
This type of memory is work of scientists from shanghai’s Fudan university who recently published a study about the new technology in the journal nature nanotechnology
Why bother creating a new kind of memory, you may wonder? Like each half of any couple, neither RAM nor ROM is perfect on its own.
While systems can quickly access data stored on Random Access Memory (RAM), the minute you shut your device down, RAM loses all that data.
Think about an unsaved Word document (yes, you live on the edge). The doc is there while you're using your computer because the RAM is running Word. If your computer suddenly shuts down, though, bye bye document.
Data stored on ROM is permanent. The problem is your computer can't write data to ROM as quickly. To solve this problem, the Chinese researchers say their new type of computer memory is not only the best of both worlds, but an improvement on the pair: It lets you decide how long you want the memory to hold data.
"People in the future may receive a disc in which the data is only effective for, say, three days, which elevates the security of the information," lead researcher Zhang Wei
"People can also have tailor-made flash drives with the new storage technology. The data stored inside will be regularly emptied at an appointed time."
This extra feature might make their new type of computer storage a strong competitor in the market against RAM and ROM, but the researchers don't comment on when that might happen.
Until then, RAM and ROM will continue their reign as the inseparable couple of the computing world. And we'll have to tolerate the inadequacies of both until something better comes along.
