Informal science popularization! What is the popular "memory fusion" in the mobile phone circle?

With the rapid development of the mobile phone industry, smart phones are constantly updated, and chips, cameras, screens, memories and other components are also gradually upgraded. In order to better meet the needs of users and the performance of smart phones, various application apps are getting bigger and bigger, which makes the memory of a group of "old models" users more and more tense, which in turn leads to the jam and greatly affects the experience.

A few years ago, the running memory of 4GB and 6GB mobile phones on the market was still mainstream. At present, 6GB is rare, and 8GB, 12GB or even larger mobile phones appear one after another. Then the problem is coming. Today's 12GB memory will not be enough in the next few years, which will cause the jam. How to solve it? Therefore, in the past two years, the technical terms of "memory fusion" and "memory expansion" are often mentioned in the mobile phone promotion of manufacturers, and how to reveal the secrets to everyone.

As the name implies, "fusion" in memory fusion technology refers to the fusion of mobile phone running memory and flash memory. When the running memory of the mobile phone is not enough for users to use, turning on this function can make the mobile phone call part of the flash memory as the running memory temporarily, thus ensuring that the mobile phone can run games and application apps smoothly and ensure the efficient operation of the mobile phone. This memory calling method is similar to PC-side virtual memory technology and cloud hosting function of network disk, but the same technical principle, mobile phone manufacturers have given different naming methods: memory fusion, memory expansion and memory Turbo.

As we know, the memory of mobile products such as computers and mobile phones is a general concept, which is generally divided into RAM (running memory) and ROM (flash memory) according to the purpose. RAM is a storage container that directly exchanges data with CPU. Users can read and write at any time, which is very fast, but it will lose the storage content in the case of power failure, so it is suitable for storing data in a short time and can also be used as a buffer.

ROM (flash memory) is a long-life, nonvolatile storage container, which can still retain the stored data when power is cut off. It acts like a hard disk in a computer and is used to store data files such as pictures, videos and music in a mobile phone.

Usually, in the "8+ 128GB" parameter introduced by mobile phone manufacturers, 8GB refers to the running memory. The bigger it is, the smoother we run software and applications, and even if more applications are opened, it will not get stuck. 128GB naturally refers to the flash memory capacity. The larger the capacity, the more data files can be stored.

Generally speaking, DRAM chips are used for running memory and NAND Flash chips are used for flash memory. The former is much more expensive per GB than the latter. At present, 8GB of running memory is mainly used in the market, and 12GB and 16GB of memory often appear on mid-to high-end models.

At present, Meguiar's, Hynix's and Samsung's brands account for more than 90% of the DRAM market share, and domestic memory chip manufacturers are shipped by Changxin Storage only in 20 19 years. Not to mention that a few brands monopolize the industries behind this abnormal market share, they will also use patented technology to lock their throats, hinder the development of domestic enterprises, and may even maliciously lower production capacity and raise prices for profiteering.

Back to the topic, after the above explanation, we can easily understand the principle of memory fusion technology, so where is the upper limit of this way of borrowing chickens to lay eggs? What is the performance of major mobile phone manufacturers?

After understanding the working principle of memory fusion technology, we can see that memory fusion can effectively increase the memory space of mobile phones, especially for low-end users running high-profile game apps. Of course, the extent to which major brand manufacturers can adapt depends on the specific process.

At present, nine mechanisms including vivo brands X60/Pro/Pro+, iQOO7 and iQOO Neo5 support memory expansion technology, and the memory capacity of mobile phones that do not expand is also different. For example, 4GB of running memory can be expanded by 5 12MB, and 8GB of running memory can be expanded by up to 3GB.

Compared with vivo, OPPO is more radical, providing three gears (2GB, 3GB and 5GB) to choose from, supporting up to 7GB of memory expansion, which can make multiple large-scale game applications run smoothly at the same time. Taking Reno5 as an example, on the premise of 12GB memory, the equivalent running memory can reach 19GB by expanding 7GB memory, which is very helpful to improve the running fluency of mobile phones. At present, many models, including Reno5 series, support memory expansion, so interested users may wish to check the phone setting options for experience.

The adaptation progress of Huawei and Xiaomi is relatively small. At present, Xiaomi brand only supports 2GB memory expansion on Redmi Note 10 models, and Huawei Mate40 series also supports 2GB memory expansion. Of course, the subsequent adaptation progress depends on official news.

It should be noted that the premise of memory fusion application is that the mobile phone will not start until it runs out of memory. The mobile phone supporting memory fusion calls idle flash memory as running memory, which can effectively improve the fluency of switching multiple applications in the background, help the mobile phone system to carry out deep optimization and control, reduce the preloading time of application startup, and improve the opening speed of large-scale applications and games. For old users, it can prolong the service life of mobile phone memory and optimize the experience.

We know that due to the increase in power consumption brought by 5G communication, manufacturers will choose to tackle the problem of APP background detention in the system in order to extend the battery life of mobile phones, and memory integration will bring users more flexible application space. In addition, the functional adaptation of Android phone manufacturers is usually faster than that of Apple. Huawei, Xiaomi, OPPO and vivo have all adapted to this technology, and I believe other brands will also be popular with this technology. Users may welcome new functions, new trends and new experiences at the industry level.

In fact, looking back, memory fusion technology gives people a sense of sight when ideas come true. As early as ten years ago, some people imagined whether the virtual memory of Windows system and ZRAM technology could be applied to Android system to solve the problem of insufficient mobile phone memory. After many years, it was finally applied to smart phones. Is it a publicity stunt or a real technological breakthrough?

The author thinks that the rapid popularization of memory fusion technology is related to the current domestic mobile phone market environment. Out of concern for users of old models, manufacturers are unwilling to accept the question of backward technology. Just like DC dimming, after a domestic mobile phone manufacturer applied, fans of other brands urged the manufacturers to adapt in the spirit of "I don't need it, you can't live without it". Huawei, OPPO, vivo, and Xiaomi quickly promoted this technology out of fear of being backward in technology. At the same time, we can also promote the sales of our products through the consumer psychology of "the greater the storage, the smoother the mobile phone and the stronger the performance". Why not?

Of course, in addition to the promotion of product selling points, this technology is more out of concern for users' psychology. We know that insufficient memory is one of the important reasons why users frequently change their mobile phones. The introduction of this memory optimization technology by manufacturers undoubtedly gives users a longer service life, which is obviously not good news for manufacturers with extremely fast product line updates. Moreover, because of the industry process, the running memory of mobile phones is getting bigger and bigger, and there is rarely a lack of memory. The memory fusion technology for key objects is obviously not the latest or high-end machine.

With the popularization and adaptation of memory fusion technology, users with older models and smaller memory will have a better mobile phone experience. I believe this is the original intention of all families to actively promote new technologies. What do you think of this?
