Can a memory card store things? The memory card is placed there

You can't store anything. As soon as the memory card on the computer loses power, all the contents on it disappear.

It can be called a memory card, which generally refers to the memory card on the mobile phone, which is a built-in memory card that can store data. The memory on the computer is called memory, which can only be used to store data temporarily, and will be lost after shutting down and powering off.

The memory card should be able to store things.

Take memory sticks, for example.

There are several black squares on the memory module, those are storage particles, each storage particle has a certain capacity, and the total capacity of a memory is the sum of the capacity of all the storage particles on it.

On the one hand, if the capacity of each storage particle is the same, the capacity of the storage particle will be larger, for example, some memory has storage particles on only one side, and some memory has both sides. On the other hand, as the process progresses, the volume of transistors becomes smaller and smaller, so that the same volume of memory particles can accommodate more transistors, that is, the larger the capacity, so that the same number of memory particles can have a larger capacity.

Memory cards are similar.

In fact, under the same process, to increase the capacity, the number of transistors will increase, and the volume will also increase. But in order for SD cards of different capacities to be used by the same device, they are added with shells that make them all look the same size.

Of course, it is also possible to use more advanced processes to make larger volumes of storage particles on the same volume.

For such a large capacity span as 64M and 1G memory cards, there are often two reasons mentioned above, and the 1G storage particles made with more advanced processes may be smaller than the 64M storage particles made with the old process.

Summary. Memory card (English: memory card, alias:

Memory card, flash memory card, flash card) is a solid-state electronic flash memory data storage device, mostly in the form of cards or cubes. It generally uses a flash (flash memory) chip as the storage medium. It is mainly used for mobile phones, digital cameras, PDAs and laptops, **** devices, handheld game consoles and other electronic devices.

It provides a form of memory that can be read and written repeatably without the need for an external power supply.

The memory card is placed there

The memory card is placed in the card slot of the phone. The method of checking the memory card of the mobile phone is as follows: 1. Turn to the side of the mobile phone, and then take the card pin of the mobile phone to top the small hole on the slot.

2. Then the card tray of the mobile phone will pop up and pull the card tray out. 3. After the card tray is drawn, you can see the memory card of the phone.
