Virtual RAM, Dynamic RAM Expansion, Extended RAM - These are the words you might have heard of recently released smartphones. Every smartphone has RAM, which everyone knows. However, the virtual RAM or "extended RAM" of the phone is a very new concept.
Currently only a few devices have seen this feature, but in the future many smartphones will see this feature. Let's take a look at the details of what a virtual RAM is and how it works.
What is Virtual Radam?
To understand the concept of virtual RAM, you must first understand what RAM is. RAM on a smartphone is a temporary memory that is much faster than other types of storage. When an app is opened on a smartphone, it is called a process. And these processes are stored in the physical memory, that is, in RAM. RAM can be used to load apps without lag and delay.
Virtual RAM, on the other hand, also uses storage, but it uses the phone's storage instead of direct RAM. Simply put, virtual RAM is used to increase RAM performance by using a certain amount of the phone's internal storage as RAM. The word "virtual" in the name implies that it is not part of the original RAM, but only part of the internal storage.
For example, if a phone has 8 GB RAM and 128 GB storage and 3 GB virtual RAM, then the phone will have a total of 9 GB of RAM and 125 GB of internal storage can be used.
How does virtual RAM work?
Those familiar with the Linux operating system will already know that the virtual RAM feature came from computers to smartphones. This feature has been in the computer for many years. Although this feature has been used on smartphones for so long using root, now this feature is becoming more and more available for the benefit of official virtual RAM. Basically the amount of virtual RAM depends on the device. Phones with extended RAM from 1GB to 6GB have already hit the market.
The amount of virtual RAM that you will use after launching the virtual memory feature will be used from the storage of the phone. However, it is vital to restart the phone after the feature is turned on. For example: Realmy Norjo 30 5G phone has 6 GB RAM, whereas if you use 5 GB virtual RAM, the total RAM will be 11 GB.
Now let us know about the application of this virtual RAM feature in real life. First, increasing the amount of virtual RAM will not increase the amount of RAM used by the system, but will use the phone's storage as virtual RAM. In the same way the amount of storage will be reduced from the storage of the phone, but the physical RAM will remain the same.
What and how does virtual RAM work on Android?
Examples of the use of virtual RAM
Let's take a look at an example to better understand how virtual RAM works. Suppose you have 10 apps running on your Android phone and there is no space left in the main RAM of your phone. In this case, one or more of the first apps launched in the background and dynamic tasks in the background close. We have all read about this problem.
The ideal solution to such problems is virtual RAM. For apps that have no dynamic function in the background, virtual RAM is used to hold the app in the background for a long time. The apps that are more important will be kept in RAM by the Android system and the rest of the apps will be stored in virtual RAM.
Apps like calculators that have no dynamic tasks in the background can be active in the background for a long time using virtual RAM. Virtual RAM means that the storage of the phone is relatively less powerful than normal RAM. So it is not possible to store games or payment apps in virtual RAM. For this reason, heavy apps are stored in real RAM.
Virtual RAM will only work when the physical RAM is fully utilized. Android devices will be able to capture more apps in the background using the virtual RAM feature RAM. Note that Gaming Performance Boost is not available with Virtual RAM. In other words, in the case of virtual RAM gaming will not be of any direct use.
Why did the virtual RAM feature come on the phone?
We already know that this virtual RAM feature of smartphones is not a new technology. Computers have had this feature for many years. Thanks to the heavy apps and games of the smartphone, this virtual RAM feature has finally come to the smartphone.
Even a few years ago, 2 GB of RAM was enough for a smartphone. However, over time, the size of the apps has increased and it takes more resources. Since it is not possible to add more RAM due to hardware limitations, using virtual RAM is a reasonable decision. This makes it possible to provide additional memory to the users while keeping the cost of building the smartphone the same.
For example, having 5G on a smartphone is not necessary now, but it will definitely be useful in the future. The concept of virtual RAM is a lot like that. The virtual RAM feature could be a great addition to smartphones in the near future.
Resource heavy apps / games like Chrome, Pubji, or Genshin Impact take up a lot of RAM on the phone. This extra radam can be very useful in such a situation. Also 8K resolution video recording and AR apps are becoming mainstream day by day. These apps will work quite well in the future for the benefit of virtual RAM.
Is it possible to increase RAM on Android phone?
It is possible to increase the total amount of RAM by rooting the Android phone and using the memory card as RAM. Also with the virtual RAM feature it is quite easy to increase the RAM of the smartphone without any problem.
Does the phone run fast if the RAM of the Android phone is cleared frequently?
The advantages and disadvantages of frequent RAM clearing exist in both directions. Since RAM is free when you clear RAM, then the apps you enter will run faster. Closing the app again, it takes some time to restart the app. So the cleared apps may take longer to launch than before.
Virtual RAM is more useful in which category of device between budget and premium devices?
Virtual RAM works on any budget type device. However, since RAM is less in budget devices, virtual RAM is more useful in budget devices.
Can Virtual RAM Increase Through Updates?
Yes, smartphone companies can increase the amount of virtual RAM through OTA updates. Virtual RAM is just a software feature, so even on phones that do not have virtual RAM, it is possible to add a virtual RAM feature through updates for its creators.
