The two most important types of computer memory, ROM and RAM, complement each other perfectly. In the past, we only needed these memories, but now we have a third, and we can do everything and even a little more than the other one.
Read-Only Memory (ROM) content that can only be read-only data can not be changed, and the burned data is final. ROM ensures that your computer, tablet, smartphone, etc. you can start the system (get in).
RAM (Random Access Memory) Any random access memory or random access memory is a random access memory device that, in contrast to ROM, is not only readable but also writable. The data will only be retained until the machine is switched on if it is no longer in power (if switched off), then lost. RAM allows you to run programs on your computer and other devices.
In the past, we only needed these memories, but now we have a third, and we can do everything and even a little more than the other one.
The new memory, the Shanghai Fudan University, had to be developed because neither ROM nor RAM itself was perfect. The system can quickly access RAM if it is switched off or, in the worst case, a power outage, we lose all unrecorded data, including our latest Word document. ROMs are in vain for data storage, data can not be written immediately and quickly.
According to Chinese researchers, the new memory has the best properties of both types and has been improved because we can decide how long it will store data.
“In the future, we can have our own discs, for example, to keep data for only three days. This option increases information security. But new storage technologies can also be customized flash drives. The data stored on them will be removed regularly at predetermined time, “explains Zhang Wei, a research leader.
The new solution can therefore be a serious market companion for ROMs and RAMs. Researchers have not yet commented on the date of their commercial distribution.
