What is virtual RAM in Vivo, Realme, Oppo, Xiaomi smartphones and how does it work?
RAM is available on every smartphone and most users know about it. However, terms such as virtual RAM or expanded RAM may not be widely known because they are relatively new.
Although virtual RAM is currently only available on a small number of devices, in the future this feature may become an integral part of most Chinese smartphone manufacturers ’devices.
What is virtual RAM?
To understand the concept of virtual RAM, we must first understand what RAM is. Random access memory is an energy-intensive memory that runs faster than any other type of memory.
The difference between your smartphone’s non-volatile memory (ROM) and random access memory (RAM): both store data, but the former is permanent and the latter is temporary. RAM is faster than non-volatile memory, so its main function is to “hold” running applications, while a slower ROM stores data (images, videos, and other files) permanently.
Virtual RAM, on the other hand, uses the smartphone's internal memory as temporary RAM.
Simply put, virtual RAM is a portion of your smartphone’s internal memory that is used as additional RAM. As the name suggests, this is “virtual” RAM, which means that the amount of expanded RAM is not physically available on your smartphone as RAM.
For example, if your smartphone has 6 GB of RAM and 128 GB of non-volatile memory and you increase the RAM to 5 GB, technically you now have 11 GB of RAM and about 123 GB of internal memory.
Is virtual RAM an innovative solution?
Unfortunately, no. This technology is not new and is already available on Android devices and Windows system (file podkachki) with root access (https://t.me/gsmgurus_FAQ/123).
Previously, when the smartphone's RAM was 256 MB, 512 MB, this technology could benefit. But now, when almost all new smartphones have more than 4 GB of RAM, is there a benefit to this technology?
Additional information: UFS 4 internal memory is almost 3.1 times slower when comparing data read and write speeds with DDR3.1-type smartphone RAM. Also, the internal memory of the smartphone has a certain amount of write time (life), so the active use of the memory chip can also shorten the life of the smartphone.
