What does mobile phone running memory mean?

Mobile phone running memory refers to the memory used by the phone when running programs. It can only temporarily store data and is used to exchange cache data with the CPU. The running memory of a mobile phone refers to the place where programs are stored or temporarily stored when running programs. With larger running memory, the mobile phone can open more programs.

What does mobile phone running memory mean

Mobile phone running memory refers to the memory used by mobile phones when running programs (that is, running memory, referred to as running memory), which can only be temporarily stored Data, used to exchange cache data with the CPU. Generally refers to random access memory (RAM), which itself cannot be used to store data for a long time. It is equivalent to the computer's memory, that is, RAM.

The running memory of a mobile phone refers to the place where programs are stored or temporarily stored. With larger running memory, the mobile phone can open more programs. If the capacity is sufficient, it will not increase the speed of running programs much. , it can only be said that larger running memory can better ensure the normal operation of the mobile phone.

There is also a kind of memory in the mobile phone, which is the "non-running memory" of the mobile phone, which is equivalent to the hard disk of the computer, that is, ROM. The larger the RAM, the phone can run multiple programs smoothly; the larger the ROM, just like the larger hard drive, it can store more data.

ROM is equivalent to the hard disk on a PC, used to store and save data. ROM is able to retain data even when the power is off. System files on your phone, or pictures, music, photos, etc. are usually stored here.

Taking the Xiaomi Note 7 Pro mobile phone as an example, the steps to check the running memory of the mobile phone are as follows:

1. First, find the settings on the Xiaomi Note 7 Pro main page;

2. Then find "About phone" in the settings interface;

3. Finally, find "About phone" in the About phone interface You can see the running memory (ram) of the phone. For example, the running memory in the picture below is 4G.

Expand knowledge:

Generally for Android phones, the advantages of large-memory phones will be greater, because the phone’s programs They are all read and written in RAM memory, and the reading and writing speed also has a certain relationship with the performance of the mobile phone. Larger RAM memory can bring more sufficient buffer space to the mobile phone. As the system itself and the application itself expand, the role of RAM memory becomes more obvious. However, this does not mean that large memory is necessarily more suitable.

(1) The wool comes from the sheep, and consumers will eventually have to pay for larger memory, which will inevitably increase the cost and potential power consumption of mobile phones for users.

(2) Large memory may be a marketing tool used by mobile phone manufacturers to induce consumers to choose mobile phones with large memory through parameters.

(3) Do not blindly trust the total amount of memory. Depending on the customization of the mobile phone system, the actual available running memory will also fluctuate accordingly. For example, a model has 4GB of memory, but the actual available memory space is only about 2GB.

(4) The memory on the market includes DDR4. Compared with the previous DDR3, DDR4 has greatly enhanced speed and power consumption control. Therefore, if you have a mobile phone with the same RAM capacity, you must also check whether it is DDR4 or DDR3. .

(5) The size of RAM memory will affect the speed of the mobile phone to a certain extent, but it is not a decisive factor. After all, the running speed of the mobile phone is determined by the CPU, GPU, RAM, ROM, and system optimization.
