Problems solved by technology
This method uses test data to obtain a part of memory reliability decline law, and it takes a lot of time for testing and model building before it has the ability to effectively prevent failures
At the same time, due to the problem of process differences in the manufacturing process, even different memories of the same model have different reliability degradation laws.
The prediction methods currently used can only be applied to the memory types that have been tested and modeled, and cannot effectively prevent failures for memory types that have not been modeled

The invention provides a storage medium reliability grade judgment method and system based on reinforcement learning, a storage medium and computing equipment, and the method comprises the steps: obtaining a system storage state of at least one storage unit in a storage system, and transmitting the system storage state to an agent, wherein the agent determines a reliability level judgment action corresponding to the storage unit based on the system storage state; performing accuracy evaluation on the reliability level judgment action through the storage system to obtain an evaluation result, and generating an evaluation feedback parameter according to the evaluation result; and transmitting the evaluation feedback parameter to the agent, and optimizing and updating the agent based on the evaluation feedback parameter. Based on the scheme provided by the invention, dynamic optimization can be carried out according to the actual operation environment, the method is suitable for different types of storage media, and the relationship between the reliability of the storage media and the characteristic parameters does not need to be obtained through pre-testing.
Description
technical field [0001] The invention relates to the technical field of flash memory life prediction, in particular to a storage medium reliability level judgment method and system based on reinforcement learning, a storage medium, and a computing device. Background technique [0002] With the development of electronic technology, memory, as the carrier of data stored in electronic equipment, has become more and more important in modern life. Reduced reliability has always been one of the major problems with data storage. During the use of the memory, various errors will occur in the data stored in its unit, which will eventually lead to the failure of the storage unit. If the storage medium generates uncorrectable data errors during operation, it will affect the normal use of the entire storage system, and even lead to loss of important data. . [0003] In order to prevent the failure of the memory, some chips are tested in the field at present, and a prediction model is e...
