[0002] Solid-state storage products that use NAND FLASH as storage media, including SSD / UFS / eMMC / SD Cark / UDisk, etc., can form a variety of application scenarios because they have a variety of application requirements, a wide variety of performance indicator requirements, and reliability requirements under different life cycles.

[0003] Solid-state storage devices require algorithm design, function development, performance tuning, effect verification, and stability testing for the application scenarios under the above combinations during the product development phase. FOB (Fresh Out of Box) refers to the state of the solid-state storage device when it is just shipped from the factory. Its internal firmware data and NAND FLASH are all in the initial state, so it has the best performance indicators. In addition to FOB, the rest must be based on certain preconditions and application scenarios after NAND FLASH is used. We call them different steady states of solid-state storage devices.

[0004] Currently, two methods are used to allow solid-state storage devices to quickly enter a steady state. One is to perform wear tests based on real solid-state storage devices to allow the solid-state storage devices to enter a steady state with different preconditions; the other is to perform simulation tests based on solid-state storage device emulators to quickly enter different test conditions. However, the first method requires traversing more steady-state test scenarios and consumes more samples; the traversal test cycle is long and the trial and error cost is high.

[0043] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] For easier understanding, see Figure 1 , an embodiment of a method for steady-state entry of a solid-state storage device provided by the present application includes:

[0045] Step 101: Read device information of a target solid-state storage device in different steady states through a host according to a preset read instruction, where the device information includes master control, cache and medium information.

[0046] Furthermore, step 101, before that, also includes:

[0047] Pre-test the target solid-state storage device to achieve different stable states.

[0048] It is understandable that solid-state storage devices are composed of four parts: main control, cache, NAND FLASH chip and PCBA. The first three have a major impact on solid-state storage devices. The main control has volatile memories such as TCM and SRAM, which are responsible for maintaining the running status of the firmware FW. The cache is generally composed of volatile memory, DRAM. The NAND FLASH chip is the data retention medium of the solid-state storage device, which stores user data, FW key tables and other information.

[0049] Before reading information from the target solid-state storage device, some preset pre-tests are required. The purpose of the test is to make the target solid-state storage device enter a steady state. Then the host responds to the preset read instruction and can read the device information of the target solid-state storage device in different steady states; each steady state is associated with its device information. The device information includes but is not limited to the master control, cache and media information.

[0050] Step 102: perform image processing and format naming processing on the device information to build a steady-state image file library, which includes multiple steady-state image files.

[0051] Furthermore, step 102 includes:

[0052] Mirror the device information according to preset rules to obtain a mirror file;

[0053] The image files are named according to the format and a steady-state image file library is constructed.

[0054] It should be noted that the preset rules can be set according to the actual situation and are not limited here. The preset rules are used to mirror the read device information to form an image file. The image file is then named according to the format, and each name corresponds to a different steady state and the corresponding device information. In this way, a steady-state image file library can be constructed. Naming the file can facilitate the subsequent quick search for the required image file, speed up the processing speed, and improve the efficiency of steady-state entry. For the specific steady-state image file library construction process, please refer to Figure 3 , is the process of collecting device information under different steady states and forming an image file library.

[0055] See also Figure 4 In the image file saving format, at the beginning of each segment of raw data, there is a header to describe its attributes. Memory_type is used to identify whether the data segment belongs to the master, cache or NAND FLASH. Load_address is used to indicate the specific data loading location. If the attribute is the master, it identifies which core it is and which addressing location of the core to load to. If the attribute is cache, it is the addressing location of the cache. If it is NAND FLASH, its specific physical address must be identified, including CHIP, DIE, BLOCK, PLANE, PAGE and other information.

[0056] The image file name consists of two parts: steady-state case + product model. The steady-state case needs to accurately describe the listed component preconditions. Because different products have different master control, cache, and particle selection, the product model needs to accurately indicate which product it is obtained from to avoid subsequent loading on the wrong product, resulting in execution errors.

[0057] Step 103: The host sends the target steady-state mirror device information to the target solid-state storage device according to a preset write instruction, and quickly enters a stable state. The target steady-state mirror device information is selected from the steady-state mirror file library.

[0058] Further, step 103 includes:

[0059] The host queries the expected steady-state image file from the steady-state image file library to obtain the target steady-state image device information;

[0060] The host sends the target steady-state mirror device information to the target solid-state storage device according to the preset write instruction, so that the device completes the write operation and quickly enters the stable state.

[0061] It should be noted that the preset read instructions and the preset write instructions are preset instructions agreed upon by the host and the target solid-state storage device, so the host's read operation is not performed randomly, but is an operation within certain constraints.

[0062] During the process of testing the target solid-state storage device, if the device needs to reach a certain steady state, the desired image file, that is, the expected steady-state image file, can be found in the steady-state image file library according to the format naming, which includes the target steady-state image device information; then the host can send the target steady-state image device information to the target solid-state storage device according to the preset write instruction, and the information sent includes the master control, cache and media information, etc.; after the target solid-state storage device receives the target steady-state image device information, it can write to the corresponding location as required, and the solid-state storage device can then perform the corresponding steady state. This method can be used to read and write steady states in different scenarios, and the more times the steady state is repeatedly entered, the more significant its efficiency. For the specific writing process, please refer to Figure 5 , that is, the process of the target solid-state storage device entering a steady state.

[0063] If the time to enter a steady state is A, the time to read and generate the image file is B, and the time to load the image file is C. Then 20 steady state experiments are performed. The time consumption of the first method in the background technology is 20 × A, and the time consumption of the method proposed in this embodiment is A+B+20×C. Given A is 72 hours, B is 1 hour, and C is 2 hours, the time consumption of method 1 is 1440 hours, while the time consumption of the method proposed in this embodiment is 113 hours, which shows that the degree of time saving is obvious.

[0064] See also Figure 6 , the state of the target solid-state storage device after writing the steady-state device information is the expected stable state, all sections of the image file are sent, the solid-state storage device is also written, and it enters the steady state successfully and quickly.

[0065] In this embodiment, when a solid-state storage device enters a specified stable state, by adding a specific read command in the FW, the host reads out all the memory, cache and NAND FLASH chip data of the solid-state storage master and saves them as a mirror file. After that, if the solid-state storage device needs to enter the same stable state again, the host loads a different stable state mirror file, and writes all the memory, cache and NAND FLASH information of the master in the mirror file to the corresponding device of the solid-state storage device through a specific write command of the FW. At this point, the solid-state storage has all the information in different stable states.

[0066] The steady-state entry test method proposed in this embodiment quickly restores the steady state by loading the image file to the sample, without the need to run a large number of pre-real tests, saving test samples and experimental time, reducing the life wear of the experimental samples, and reducing the experimental cost. Rapidly entering the steady state in the real sample, rather than just in the simulation, can obtain more comprehensive and accurate experimental results.

[0067] The solid-state storage device steady-state entry method provided by the embodiment of the present application converts the device information of the target solid-state storage device in different steady states into an image file to generate a steady-state image file library; then, when the solid-state storage device needs to enter different steady states, the existing files in the write library, i.e., the device information, are loaded; this process does not require multiple steady-state entry times; and the device information written in different steady states does not have too many requirements on the number of samples, and the steady-state entry test can be implemented on one sample, adapting to the test needs of a variety of different steady-state scenarios, and can improve the design and development efficiency of the product. Therefore, the embodiment of the present application can solve the technical problems that the existing solid-state storage device quickly enters the steady state with a long test cycle, many test limitations, and may be difficult to ensure the accuracy of the test.
