[0051] In the following description, a large number of specific details are given to provide a more thorough understanding of the present disclosure. However, it is obvious to those skilled in the art that the present disclosure can be implemented without one or more of these details. In some embodiments, in order to avoid confusion with the present disclosure, some technical features known in the art are not described; that is, all features of the actual embodiment may not be described here, and well-known functions and structures may not be described in detail.

[0052] Generally, terms can be understood at least in part from their use in context. For example, depending at least in part on the context, the term "one or more" as used herein can be used to describe any feature, structure or characteristic in a singular sense, or can be used to describe a combination of features, structures or characteristics in a plural sense. Similarly, terms such as "one" or "the" can also be understood to convey singular usage or to convey plural usage, depending at least in part on the context. In addition, the term "based on" can be understood to not necessarily be intended to convey an exclusive set of factors, and can alternatively allow for the presence of additional factors that are not necessarily explicitly described, which also depends at least in part on the context.

[0053] Unless otherwise defined, the purpose of the terms used herein is only to describe specific embodiments and is not intended to limit the present disclosure. When used herein, the singular forms "one", "an" and "said / the" are also intended to include plural forms, unless the context clearly indicates another way.

[0054] In order to thoroughly understand the present disclosure, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present disclosure. The preferred embodiments of the present disclosure are described in detail below, but in addition to these detailed descriptions, the present disclosure may also have other implementations.

[0055] Mobile phones are widely used as common mobile devices in daily life, but the storage capacity of mobile phones is limited and can be easily filled up. As the behavior of storing large amounts of data (e.g., saving short videos, movies, TV series, audio) becomes more and more common, users need larger storage capacity. Therefore, additional storage space needs to be provided.

[0056] Mobile storage has the advantages of being rewritable and having a large storage capacity, and is therefore favored by consumers. Mobile storage includes but is not limited to USB flash disks, mobile hard disks, memory cards, etc. By backing up the data in a mobile phone to a mobile storage, additional storage space can be provided for the mobile phone and the mobile phone memory can be freed up. However, in this solution, users need to purchase and carry both a mobile phone and a mobile storage product, which increases the user's usage cost and reduces portability.

[0057] Moreover, backing up data in a mobile phone to a mobile storage usually requires the use of other devices, which makes the user experience poor. For example, the mobile phone and the mobile storage are connected to the computer respectively to copy the data; after the copy is completed, the mobile phone and the mobile storage are unplugged from the computer. In addition, users also need to purchase matching data cables, which further increases the user's usage cost and further reduces the portability.

[0072] In some embodiments, the switching instruction includes a first sub-switching instruction; wherein the first sub-switching instruction is used to instruct switching to the second state; the mobile device 100 further includes: a processor 110, the processor 110 is coupled to the first memory 120;

[0073] The switching circuit 150 includes: a first port, a second port and a third port, the first port is coupled to the first memory 120, the second port is coupled to the memory system 130, and the third port is coupled to the external interface 160;

[0074] The switching circuit 150 is specifically configured to: in response to a first sub-switching instruction from the processor 110 , switch the first port from being coupled to the third port to being coupled to the second port.

[0075] The processor 110 includes a dedicated processor, for example, a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processor (DSP), a tensor processing unit (TPU), a video processing unit (VPU), etc. At least one of the multiple dedicated processors.

[0076] For example, refer to Figure 1 and Figure 2 As shown, when the processor 110 needs to access the memory system 130, the processor 110 may send a first sub-switching instruction to the switching circuit 150; the switching circuit 150 switches from the A-C connection to the A-B connection in response to the first sub-switching instruction, so that the processor 110 is coupled to the memory system 130 through the switching circuit 150.

[0080] Reference Figure 2 As shown, when the switching circuit 150 switches to the second state, the memory system 130 can be used as an extended memory of the mobile device 100. Exemplarily, when the available storage space of the first memory 120 is insufficient, the processor 110 can back up the data stored in the first memory 120 to the second memory 131 of the memory system 130, and erase the backed-up data in the first memory 120, thereby releasing the running memory and / or body memory of the mobile device 100, and improving the operating performance of the mobile device 100; and by backing up the data stored in the first memory 120 to the second memory 131 of the memory system 130, data loss can be avoided and data reliability can be ensured; in addition, the data backup is completed inside the mobile device 100 without the need for other devices, which can improve the speed of data transmission and backup efficiency.

[0081] It should be noted that, in actual applications, an application program may be installed on a mobile phone, and a user may complete the switching of the circuit state and the backup of the data stored in the first memory by operating the application program.

Since the data reading is completed inside the mobile device 100, there is no need to use other devices, which can improve the data transmission speed and reading efficiency.

[0083] In the embodiment of the present disclosure, after the first port of the switching circuit is switched from coupling with the third port to coupling with the second port, the switching circuit can be switched to the second state. In this way, the memory system can be used as an extended memory of a mobile device, and backing up the data in the first memory to the memory system no longer requires the aid of other devices or supporting products, thereby enhancing the user experience, further reducing the cost of use, and further enhancing portability. Data can be backed up or read inside the mobile device without the aid of other devices, thereby improving backup efficiency or reading efficiency.

[0089] In some embodiments, the switching circuit 150 is specifically configured to: in response to a recovery instruction from the processor 110, the first port switches from coupling with the second port to coupling with the third port. In this way, the switching circuit 150 can switch from the second state to the first state.

Figure 1As shown, the mobile device 100 switches to the normal state (ie, the first state). It should be noted that, in the normal state, the mobile device 100 is usually used as a communication tool.

[0091] In some embodiments, the switching circuit 150 is specifically configured to: in response to a recovery instruction from the processor 110, the third port switches from coupling with the second port to coupling with the first port. In this way, the switching circuit 150 can switch from the third state to the first state.

Figure 1 As shown, the mobile device 100 is switched to the normal state.

[0093] It should be noted that the recovery instruction for switching from the second state to the first state and the recovery instruction for switching from the third state to the first state may be the same or different, and the present disclosure has no special limitation on this.

[0094] In some embodiments, the switching circuit 150 is specifically configured to: in response to a switching instruction from the processor 110 , the third port switches from coupling with the first port to coupling with the second port; wherein the external interface 160 is coupled to an external terminal.

[0095] For example, refer to Figure 1 and Figure 3 As shown, when an external terminal needs to access the memory system 130, the processor 110 can send a switching instruction to the switching circuit 150; the switching circuit 150 responds to the switching instruction and switches from the A-C connection to the B-C connection, so that the external terminal is coupled to the memory system 130 through the external interface 160 and the switching circuit 150, thereby achieving access to the memory system 130.
