A method for an embodiment of that present application include obtaining an operating temperature of a solid state drive (SSD); Judging whether the workingtemperature meets the first condition; Determining a target reference voltage BRP value corresponding to a memory cell if the operating temperature meets a first condition, wherein the target reference voltage BRP value is a BRP value corresponding to a bit error rate of the memory cell when the operating temperature meets a second condition; A data operation is performed on the storage unit according to a target BRP value.

Description

technical field [0001] The embodiments of the present application relate to the field of data storage, and in particular, to a data processing method and a related device of a solid-state hard disk. Background technique [0002] Solid state drives (SSD) refer to hard drives made of solid state electronic memory chip arrays, consisting of a control unit and a storage unit. The operating temperature range of the memory chip of the solid-state hard drive is very wide, commercial products (0°C to 70°C), industrial standard products (-40°C to 85°C). The commonly used solid-state electronic storage chip is NAND (no and). In practical applications, select NAND memory and cooperate with an appropriate control chip to manufacture solid-state hard drives, so it is widely used in industrial control, video surveillance, network monitoring and network terminals. . [0003] In the prior art, the operating characteristics of the solid-state electronic storage chip NAND change with temper...

Problems solved by technology

[0003] In the prior art, the operating characteristics of the solid-state electronic storage chip NAND change with temperature. Generally, as the temperature increases, the bit error rate of SSD data operations will gradually increase.

[0004] In the actual application environment, SSD needs to work in a large operating temperature range. Due to the change of SSD operating temperature, the bit error rate of SSD data operation will be greatly increased, thereby reducing the reliability of SSD data operation.
