How many kinds of memory does Apple 12 have?

The iPhone 12 has three mobile phone storage memory versions of 64GB, 128GB, and 256GB, while the running memory is 4GB. Running memory is a space used to store temporary data generated by operations, while storage memory is a space specifically used to store non-temporary data. The larger the running memory, the faster the mobile phone's computing speed.

iPhone 12 is a mobile phone product released by Apple (Apple) at 10 a.m. Western Time on October 13, 2020 (1 a.m. on October 14, 2020, Beijing time) at the ApplePark headquarters campus.

The Apple 12 has three mobile phone memory versions of 64GB, 128GB, and 256GB, and the running memory is 4GB.

What is mobile phone memory

To put it simply, mobile phone memory is actually a component used to store data. It is mainly divided into two categories, one is running memory, and the other is Classes store memory.

The so-called running memory is used to store temporary data. When the mobile phone is working, it needs to continuously call a large amount of data for calculation, and these data are often temporary and disappear after use. has value, but these data also require corresponding space to store. At this time, you only need to provide them with a smaller storage space to allow them to run.

Storage memory is a space specially used to store non-temporary data. For example, the photos, videos, chat records, etc. in your mobile phone are all non-temporary data. As long as you do not actively delete it, they will It will always exist on your mobile phone. Maybe this kind of data takes up a lot of space and is in large quantity, so the mobile phone has a storage memory specially set up to store them.

In short, memory is used to store data, temporary data is stored in running memory, and non-temporary data is stored in storage memory.

What is the difference between running memory and storage memory

Although running memory and storage memory both belong to the space for storing data, their differences are still very obvious. Running memory is somewhat similar to human brain capacity. The larger a person's brain capacity, the faster his thinking speed. In the same way, the larger the memory of this mobile phone, the faster its computing speed. On the contrary, the smaller the memory of the mobile phone, the slower the computing speed of the mobile phone will be, and the use will be laggy. Storage memory is a space for storing data. It does not require data calculations like running memory. All it has to do is put data in or move out. It only needs to have enough space. To put it bluntly, running memory is mainly responsible for mental work, while storage memory is mainly responsible for physical work.

In short, when choosing a mobile phone, try to choose mobile phones with larger running memory and storage memory. Because the larger the running memory, the smoother the phone will be used, and the larger the storage memory, the more data can be stored in the phone.
