Detailed Implementation

[0018] To make the objectives, features, and advantages of this application more apparent and understandable, 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. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] This application provides a data writing method that can be applied to a storage device or an electronic device containing a storage device. The storage device can be a hard drive, USB flash drive, or other device with storage capabilities. The electronic device can be a PC, laptop computer, or other device that includes any of the aforementioned storage devices. In this embodiment, the storage device includes multiple storage units; such as... Figure 1 As shown, the method includes: S101: The electronic device acquires environmental data of the environment in which the storage device is located and usage data of each storage unit.

[0020] In this step, the storage unit is a unit in the storage device used for storing and modifying data. The usage data of the storage unit includes key usage indicators such as the historical write count, erase count, and usage duration for each storage unit. In this embodiment, refer to... Figure 2 and Figure 3 As shown, Figure 2 This is a schematic diagram of the hardware composition of a storage device. The usage data of each storage unit can be read through the main control chip within the storage device. Environmental data of the environment in which the storage device operates can include ambient temperature, ambient humidity, etc., and this environmental data can be accessed through... Figure 2 The data is detected or read by environmental sensors (temperature sensors, humidity sensors).

[0021] S102: The electronic device determines the wear coefficient of each storage unit based on environmental data and usage data of each storage unit.

[0022] In this embodiment, it is understood that environmental factors can have a certain impact on the wear and tear of the storage cell. For example, the physical wear and tear of data reading and writing at 80°C is equivalent to 1.5 to 2 times that at room temperature. In a high-humidity environment, moisture seeps into the storage cell package and forms an electrolyte pool under the action of an electric field. Dendrite migration occurs in the aluminum pads or copper traces, which may cause word lines to short-circuit and bit lines to leak, increasing the wear and tear of the storage cell. In a low-temperature environment below 0°C, the electron mobility decreases, and the same amount of data needs to be written more times than at room temperature, increasing the wear and tear on the storage cell, etc.

[0023] Based on this, considering the different wear levels of storage units under different environments, this application determines the wear coefficient of each storage unit based on different environmental data and usage data of each storage unit. In this step, the wear coefficient of each storage unit is used to characterize the current wear level of each storage unit. It is determined jointly by environmental data and usage data. In an optional scheme, the wear coefficient of each storage unit can be determined by a pre-set mapping relationship table. The mapping relationship table includes the correspondence between different environmental data, different usage data and wear coefficients. For example, assuming the environmental data is: temperature 60 degrees, humidity 40%; usage data: 20 writes, usage time 0.5 hours, the corresponding wear coefficient is A. Assuming the environmental data is: temperature -3 degrees, humidity 60%; usage data: 40 writes, usage time 2 hours, the corresponding wear coefficient is B. S103: The electronic device determines the target storage unit based on the environmental data and the wear coefficient of each storage unit. The target storage unit is used to write the data to be written.

[0024] In this step, after determining the wear coefficient of each storage cell in step S102, in order to further reduce the wear of the storage cells and extend the service life of the storage device, this embodiment combines environmental data and the wear coefficient of each storage cell to determine the target storage cell for writing the data to be written. In an optional scheme, under the determined environmental data, the storage cell with the lowest wear coefficient is used for the data writing operation. For example, assuming the environmental data indicates that the current environment is a high-temperature environment, the storage cell with the lowest wear coefficient is used as the target storage cell for the data writing operation. This avoids randomly writing to storage cells with higher wear coefficients, thereby preventing further wear on the storage cells.

[0025] In steps S101-S103, environmental data of the storage device's environment and usage data of each storage unit are obtained; based on the environmental data and usage data of each storage unit, the wear coefficient of each storage unit is determined; based on the environmental data and wear coefficient of each storage unit, a target storage unit is determined, and the target storage unit is used to write the data to be written. This application combines the environmental data of the device's environment and the usage data of the storage units to determine the target storage unit, which can comprehensively consider environmental factors and the actual wear of the storage units to evenly distribute the data writing across each storage unit, reducing further wear and tear on the storage units and extending the lifespan of the storage unit device.

[0026] In some alternative solutions, environmental data includes ambient temperature and humidity. Based on this environmental data and the wear coefficient of each storage unit, the target storage unit is determined, including: When the temperature data is less than or equal to the first preset threshold and the humidity data is less than or equal to the second preset threshold, the storage unit with the wear coefficient less than the third preset threshold is determined as the target storage unit. When the temperature data is greater than the first preset threshold, or the humidity data is greater than the second preset threshold, the storage unit with the smallest wear coefficient among all storage units is determined as the target storage unit.

[0027] Furthermore, in some optional schemes, when the temperature data is less than or equal to a first preset threshold and the humidity data is less than or equal to a second preset threshold, after determining the target storage unit, the following steps are also included: Get the data to be written; The data to be written is written to the target storage unit based on the first write speed.

[0028] In some alternative solutions, when the temperature data exceeds a first preset threshold, or the humidity data exceeds a second preset threshold, after determining the target storage unit, the following steps are also included: The data to be written is written to the target storage unit based on the second write speed; the second write speed is less than the first write speed.

[0029] In this application, the first preset threshold and the second preset threshold are the normal reference thresholds for temperature and humidity, respectively. Figure 3 As shown, when both temperature and humidity data do not exceed the corresponding normal baseline thresholds, it indicates that the storage device is under normal temperature and humidity conditions. Storage cells with low wear (wear coefficient less than a third preset threshold, which is an empirical value) are selected from among the storage cells. These selected low-wear cells are then used as target storage cells. Based on a normal write speed (first write speed), the data to be written is randomly written to any of these target storage cells. In an optional embodiment, the data to be written can also be first written to the target storage cell with the lowest wear coefficient. When that target storage cell is full, the data to be written is then written to the target storage cell with the second lowest wear coefficient, and so on.

[0030] This embodiment, by including only storage cells with wear coefficients below a third preset threshold in the candidate pool under normal conditions, can preemptively eliminate obviously aged storage cells, concentrating subsequent writes on younger cells, significantly reducing wear differences between storage cells, and delaying the appearance of the first high-wear storage cell. Furthermore, under normal conditions, data is written at the normal first write speed without frequency reduction or other steps, so the user does not perceive bandwidth fluctuations, thus balancing wear control and user experience.

[0031] When at least one of the temperature and humidity data exceeds the corresponding normal baseline threshold, it indicates that the storage device is in an extreme environment of high temperature, high humidity, or high temperature and high humidity. In this application, it is considered that high temperature and high humidity exponentially accelerate oxide layer breakdown, metal migration, and charge leakage. Any additional write operation at this time may be the last write operation. Only the storage cell with the lowest wear coefficient and minimal physical damage can simultaneously minimize electric field stress, thermal stress, and chemical stress, avoiding immediate failure. Therefore, in extreme environments, this embodiment forces the selection of the storage cell with the lowest wear level for writing, ensuring effective data writing while avoiding further damage to highly worn storage cells. In this application, when performing write operations on the target storage cell in extreme environments, the write speed of the data to be written is reduced, i.e., a second write speed lower than the normal speed is used to write data to the target storage cell. At this time, the programming pulse width is lengthened, the peak current decreases, and the instantaneous impact of the oxide layer field strength is reduced, which can suppress further breakdown of the already degraded gate oxide of the flash memory block under extreme environments such as high temperature and high humidity. In addition, slow writing reduces the instantaneous power consumption of the target storage cell and decreases the channel temperature rise, thus preventing further temperature increases that could lead to accelerated wear of the target storage cell.

[0032] This embodiment is illustrated by... Figure 2 The temperature and humidity sensors in the memory monitor environmental factors such as temperature and humidity in real time, dynamically adjusting the write strategy. This is flexible and convenient, and can effectively reduce the wear and tear of storage units in different environments.

[0033] In some alternative solutions, the wear factor of each storage unit is determined based on environmental data and usage data of each storage unit, including: For any storage unit, Obtain the weighting coefficients for usage data and environmental data for the storage unit, respectively; The wear factor of the storage unit is determined based on usage data, environmental data, and weighting coefficients for the usage data and environmental data.

[0034] In this application, different weighting coefficients are pre-set for usage data and environmental data according to actual needs. The weighting coefficient represents the degree of influence of different data on storage unit wear; a larger weighting coefficient indicates a greater influence of the data on storage unit wear, and a smaller weighting coefficient indicates a smaller influence. The wear coefficient is calculated using formula (1): MS = f1.W + f2.E + f3.T + f4.Temp + f5.Hum (Formula 1) Where MS is the wear coefficient. W is the number of writes to the storage unit. E is the number of erases to the storage unit. T is the usage time of the storage unit. Temp is the ambient temperature. Hum is the humidity. f1, f2, f3, f4, and f5 are the weight coefficients corresponding to W, E, T, Temp, and Hum, respectively, and can be flexibly adjusted. By using formula (1) to put the number of writes, erases, usage time, temperature, and humidity into the same linear model, and using configurable weight coefficients f1~f5 to distinguish the contribution, the originally discrete and heterogeneous five indicators can be normalized into a single wear coefficient MS in the 0-1 range. This expands the calculation dimension of the wear coefficient of the storage unit, avoids the misjudgment caused by the existing technology that only relies on a single indicator to determine the wear coefficient, and more accurately determines the wear degree of the storage unit.

[0035] In some alternative approaches, the method also includes: When the wear coefficient of each storage unit is greater than or equal to the third preset threshold, the stored data in the storage unit with the highest wear coefficient is migrated to the cache for storage.

[0036] In this application, when the wear coefficient of each storage cell is greater than or equal to a third preset threshold, meaning that the wear degree of each storage cell is high, considering that the storage cell with the highest wear coefficient is approaching the physical limit of the device, the next write or read operation may trigger a word line short circuit. Therefore, this embodiment, while the data in the storage cell with the highest wear coefficient can still be read correctly, moves the data stored in it to the cache area (e.g., ...) all at once. Figure 2 Storing data in the cache module (often referred to as a cache module) is equivalent to retrieving data before the storage unit becomes completely unusable, preventing direct data loss due to storage unit failure during subsequent writes or reads. If data migration is delayed until the most worn storage unit reports an error, it often involves multiple read / write retries, introducing additional read / write amplification. Furthermore, migrating data from the most worn storage unit to the cache is equivalent to forcing the most vulnerable storage unit offline, causing the average wear coefficient of the remaining storage units to fall below the threshold again, making them writable again, and naturally extending the overall lifespan.

[0037] This application also provides a data writing device applied to a storage device, the storage device including multiple storage units; such as... Figure 4 As shown, the device includes: The first acquisition unit 401 is used to acquire environmental data of the environment where the storage device is located and usage data of each storage unit. The first determining unit 402 is used to determine the wear coefficient of each storage unit based on environmental data and usage data of each storage unit. The second determining unit 403 is used to determine the target storage unit based on environmental data and the wear coefficient of each storage unit. The target storage unit is used to write the data to be written.

[0038] In some optional schemes, the environmental data includes ambient temperature and ambient humidity. The second determining unit 403 is used to determine the storage unit with a wear coefficient less than a third preset threshold as the target storage unit when the temperature data is less than or equal to a first preset threshold and the humidity data is less than or equal to a second preset threshold; and to determine the storage unit with the smallest wear coefficient among all storage units as the target storage unit when the temperature data is greater than the first preset threshold or the humidity data is greater than the second preset threshold.

[0039] In some alternative schemes, the first determining unit 402 is used to obtain, for any storage unit, the weighting coefficients of the usage data and environmental data of the storage unit respectively; and to determine the wear coefficient of the storage unit based on the usage data, environmental data and the weighting coefficients of the usage data and environmental data.

[0040] In some optional solutions, when the temperature data is less than or equal to a first preset threshold and the humidity data is less than or equal to a second preset threshold, the following is also included: The write unit is used to acquire the data to be written and write the data to be written to the target storage unit based on the first write speed.

[0041] In some alternative solutions, when the temperature data is greater than a first preset threshold or the humidity data is greater than a second preset threshold, the writing unit is used to write the data to be written to the target storage unit based on a second writing speed; the second writing speed is less than the first writing speed.

[0042] In some alternative solutions, the device also includes: The storage unit is used to migrate the stored data in the storage unit with the highest wear coefficient to the cache area for storage when the wear coefficient of each storage unit is greater than or equal to a third preset threshold.

[0043] It should be noted that the data writing device in this application embodiment solves the problem in a similar way to the aforementioned data writing method.
