[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0030] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] Considering that existing solutions require users to use dedicated encryption applications to encrypt solid-state drives (SSDs), and these applications need to be opened every time encryption is required, this not only increases the complexity of the operation but also, since most encryption applications are limited to computer use and cannot be used on mobile devices, causing numerous inconveniences for users, this application provides an SSD and its control circuit. The control circuit of this SSD includes a switch module, allowing users to encrypt the data stored on the SSD simply by changing the state of the switch module. This ensures data security while being simple and convenient to operate, greatly increasing user convenience and improving the user experience.

[0032] The control circuit of this solid-state drive will be described below with reference to some specific embodiments.

[0033] Figure 1 A schematic diagram of the control circuit of a solid-state drive (SSD) according to an embodiment of this application is shown. An SSD is a storage device that uses solid-state electronic storage chips as the storage medium, primarily used for storing digital information. Exemplarily, the control circuit of the SSD includes: a control module 11, a switch module 12, and an encryption module 13. The control module 11 can be any type of control chip; exemplary, the control module 11 is an SSD control chip. The control module 11 is electrically connected to the encryption module 13. It is understood that the encryption module 13 can be any type of encryption chip, and the control module 11 implements hardware encryption through the encryption chip.

[0034] The switch module 12 is used to generate an encryption signal in the first state and a write-protection signal in the second state. It is understood that the switch module 12 can be any type of switch module, such as a DIP switch, a push-button switch, or a rotary switch. Specifically, the switch module 12 can have only two states, generating either an encryption signal or a write-protection signal based on the switching between these two states. For example, when the switch module 12 is on, it is in the first state, generating an encryption signal; when the switch module 12 is off, it is in the second state, generating a write-protection signal. The switch module 12 can also have two or more states, generating either an encryption signal or a write-protection signal based on the switching between multiple states. For example, when the first switch in the switch module 12 is on, it is in the first state, generating an encryption signal; when the second switch in the switch module 12 is on, it is in the second state, generating a write-protection signal; when the third switch in the switch module 12 is on, or when no switch in the switch module 12 is on, it is in the third state, and the solid-state drive can be read and written normally. The switch module 12 can be configured according to the actual application.

[0035] The encryption module 13 is used to encrypt the data stored on the solid-state drive (SSD) according to the encryption signal and control module 11. Specifically, the encryption module 13 generates one or more encryption keys. These encryption keys can be dynamic or static. Furthermore, depending on the application, the encryption chip can communicate with an electronic device to set the key. After the user sets the key in the electronic device, they can control the switch module 12 to encrypt or deencrypt the data stored on the SSD. Additionally, the encryption module 13 can encrypt data before it is written to the SSD and automatically decrypt it upon reading. The encryption module 13 can also encrypt the entire SSD, including the operating system, applications, and user data. Furthermore, the encryption module 13 can encrypt specific files or folders, providing finer-grained protection.

[0036] After the user encrypts the data on the solid-state drive by controlling the switch module 12, if the data needs to be decrypted, they only need to enter the corresponding key in the electronic device. It is understood that the electronic device in this embodiment can be any kind of electronic device, such as a computer or a mobile phone. The user only needs to set a key or enter a key on the electronic device to decrypt. Encrypting the solid-state drive only requires controlling the switch module 12, and there is no need to use the electronic device to encrypt every time. While ensuring data security, the operation is simple and convenient, which greatly increases the convenience for users and improves the user experience.

[0037] The control module 11 controls the data to be read-only based on the write protection signal. Specifically, when the control module 11 receives the write protection signal from the switch module 12, it puts the solid-state drive (SSD) into write-protected mode. At this time, data cannot be written to the SSD, and only data can be read, thus preventing unknown programs and viruses from entering and ensuring the security of the SSD.

[0038] The solid-state drive (SSD) control circuit of this embodiment includes an encryption module 13. The encryption module 13 can perform hardware encryption on the control module 11 based on signals from the switch module 12, eliminating the need for complex programming in the control module 11, thus improving system performance. Furthermore, the encryption module 13 typically incorporates physical protection measures, such as anti-disassembly detection and anti-tampering circuits, further enhancing security. The control circuit of this application includes a switch module 12, allowing users to encrypt and write-protect the SSD by controlling the switch module 12, ensuring data integrity and consistency without requiring additional operations or configurations, making it more convenient for users and greatly improving the user experience.

[0039] As an alternative solution, Figure 2 The diagram shows another structural schematic of the control circuit of a solid-state drive.

[0040] In one embodiment, such as Figure 2 As shown, based on the above embodiment, the control circuit of the solid-state drive further includes: a first connection port 14 and a second connection port 15, with the control module 11 electrically connected to the first connection port 14 and the second connection port 15 respectively. It is understood that the first connection port 14 can be any type of connection port; it can be a USB interface, a Type-C interface, or a SATA interface. Similarly, the second connection port 15 can be any type of connection port; it can be a USB interface, a Type-C interface, or a SATA interface. The second connection port 15 can be the same type as the first connection port 14, or it can be a different type of connection port. Exemplarily, the first connection port 14 is a Type-C interface, and the second connection port 15 is a USB interface, enabling the solid-state drive to support multiple protocols and meet the connection needs of different devices.

[0041] The solid-state drive (SSD) control circuit of this embodiment has two connection ports, providing more connection options to adapt to different usage scenarios, improving the flexibility and compatibility of the SSD, and making it suitable for different application scenarios and devices. The USB and Type-C interfaces are highly universal and support various electronic devices. Users can insert or remove the SSD without turning off the device, improving ease of use. At the same time, it can provide power support to the SSD, improving its reliability.

[0042] In one embodiment, such as Figure 2 As shown, based on the above embodiment, the control circuit of the solid-state drive further includes: a bridging module 16, one end of which is electrically connected to the control module 11, and the other end of which is electrically connected to the first connection port 14 and the second connection port 15 respectively. Specifically, the bridging module 16 is used to perform protocol conversion, converting the storage protocol inside the solid-state drive into the USB protocol, thereby enabling the solid-state drive to communicate with electronic devices through a USB interface or a Type-C interface. For example, the bridging module 16 converts the SATA protocol into the USB protocol, enabling the SATA solid-state drive to connect to electronic devices through the USB interface; the bridging module 16 converts the PCIe protocol into the USB protocol, enabling the PCIe solid-state drive to connect to electronic devices through the USB interface; the bridging module 16 converts the NVMe protocol into the USB protocol, enabling the NVMe solid-state drive to connect to electronic devices through the USB interface.

[0043] In this embodiment, the solid-state drive control circuit is equipped with a bridging module 16 for protocol conversion. The bridging module 16 supports multiple storage protocols and USB protocols without the need for additional adapters or converters. Using the bridging module 16, the solid-state drive can achieve efficient, convenient, and secure data transmission, meeting the needs of various application scenarios.

[0044] In one embodiment, such as Figure 2 As shown, based on the above embodiment, the control circuit of the solid-state drive further includes a power module 17. The input terminal of the power module 17 is connected to a power source. The power module 17 is used to perform voltage conversion on the power source to provide the operating power required by the control circuit of the solid-state drive.

[0045] The power module 17 can provide only one power signal to power the control circuit of the solid-state drive, or it can provide multiple different power signals to power the control circuit of the solid-state drive. The power module 17 can be configured according to the actual application. The power module 17 can be equipped with a power chip, a voltage regulator, a Zener diode, etc.

[0046] In this embodiment, the solid-state drive control circuit is powered by a power module 17. The power module 17 can provide a stable voltage output, ensuring that the solid-state drive can obtain the required power under various working conditions, avoiding performance degradation or data corruption caused by voltage fluctuations. Furthermore, it can also provide short-circuit protection, surge protection, and overvoltage protection for the circuit, greatly improving the stability and reliability of the solid-state drive.

[0047] This application also provides a solid-state drive, which, by way of example, includes the control circuitry described above.

[0048] As an alternative solution, Figure 3 The diagram shown is a structural schematic of a solid-state drive.

[0049] In one embodiment, such as Figure 3 As shown, based on the above embodiments, the control circuit of the solid-state drive further includes a storage module, which is electrically connected to the control module 11. It is understood that the storage module can be any type of non-volatile storage module; exemplaryly, the storage module is flash memory, such as NAND flash.

[0050] In this embodiment, the solid-state drive (SSD) uses Flash memory for storage, ensuring high capacity, achieving high-speed read and write, and reducing the cost of the SSD.

[0051] In one embodiment, such as Figure 3 As shown, based on the above embodiment, a first connection port 14 is provided at one end of the solid-state drive (SSD), and a second connection port 15 is provided at the other end. Distributing the first connection port 14 and the second connection port 15 at opposite ends of the SSD can disperse the stress during connection, making the SSD more balanced and enhancing its physical stability. Furthermore, dispersing the connection ports can reduce the formation of localized hot spots and improve overall heat dissipation.

[0052] Depending on the actual application, other modules of the SSD can be set in the middle area of ​​the SSD. Furthermore, a casing can be added to the SSD. For example, Figure 3 As shown, the switch module 12 is located on one side of the solid-state drive (SSD). Controlling the switch module 12 controls the SSD's encryption or write protection. It is understood that the switch module 12 is a mechanical switch, and its settings can be configured according to actual application requirements. For example, tossing the switch module 12 to the left can be the first state, generating an encryption signal; tossing it to the right can be the second state, generating a write protection signal; and setting the switch module 12 to the middle position represents the SSD's normal read / write mode. Positioning the switch module 12 on one side of the SSD facilitates user operation and avoids interference from the connection ports.

[0053] In this embodiment, the first connection port 14 and the second connection port 15 are respectively located at both ends of the solid-state drive, which improves the physical stability and connection reliability of the solid-state drive. The switch module 12 is located on one side of the solid-state drive, making the front and back of the solid-state drive simpler and improving the overall aesthetics of the product.
