00:00:00,866 --> 00:00:05,666

In this lesson, we will talk about temporary storage, cache, SDRAM

2

00:00:06,200 --> 00:00:10,200

There are two types of memory in mobile phones, ROM and RAM

3

00:00:10,566 --> 00:00:12,300

RAM is random access memory,

4

00:00:12,500 --> 00:00:14,133

ROM is read only memory

5

00:00:15,300 --> 00:00:17,600

RAM is equivalent to the memory of the computer,

6

00:00:17,966 --> 00:00:20,500

and is referred to as temporary storage,

7

00:00:20,600 --> 00:00:23,033

cache or running memory on the mobile phone

8

00:00:23,233 --> 00:00:27,733

The memory used when running the program can only temporarily store data,

9

00:00:27,900 --> 00:00:31,100

and is used to exchange cache data with the CPU,

10

00:00:31,266 --> 00:00:34,333

and cannot be used for a long-term storage of data

11

00:00:35,300 --> 00:00:38,333

Its size will affect the running speed of the system

12

00:00:39,833 --> 00:00:43,200

Common ones are 6G, 8G, 12G,

13

00:00:44,033 --> 00:00:46,933

these refer to the running memory of the mobile phone,

14

00:00:47,800 --> 00:00:51,066

it is a memory chip that can only temporarily store data

15

00:00:55,933 --> 00:00:58,133

For example, in the picture on the right,

16

00:00:58,800 --> 00:01:02,200

the frame selected is the temporary storage on the mainboard

17

00:01:03,100 --> 00:01:06,600

CPU, Font library, Temporary storage

18

00:01:06,900 --> 00:01:11,266

Some mainboards have the temporary memory soldered to one side separately,

19

00:01:11,600 --> 00:01:15,266

so not all the temporary memory is soldered on the CPU

20

00:01:16,566 --> 00:01:18,966

This is a Micron temporary storage,

21

00:01:19,066 --> 00:01:22,433

this is a SanDisk hard drive, here is the CPU

22

00:01:25,100 --> 00:01:28,900

The most used temporary brands in mobile phones are as follows

23

00:01:31,266 --> 00:01:35,533

The model starts with SEC represents Samsung temporary storage

24

00:01:36,833 --> 00:01:41,600

The model starts with SKhy represents Hynix temporary storage

25

00:01:43,266 --> 00:01:48,466

The mark M on the temporary storage represents the temporary storage of Micron

26

00:01:49,633 --> 00:01:51,800

Ok, that's it for this lesson
