Embodiment Construction

[0057] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0058] refer to figure 1 , is a kind of SSD data loss prevention method disclosed by the present invention, comprising:

[0059] S1: Obtain the working temperature information of the SSD at the moment of power failure;

[0060] The power-off request of the SSD is obtained first, and after the power-off request is obtained, the operating temperature of the SSD is obtained and stored.

[0061] S2: Obtain the current external temperature information;

[0062] Determine the current application scenario information, find the temperature sampling method corresponding to the current application scenario information from the corresponding relationship between the current application scenario information and the temperature sampling method, and obtain the sampling interval time information in the temperature sampling method information. Obtain the sampling temperat...

Abstract

The invention relates to the field of data storage, and discloses an SSD data loss prevention method and a system, and an SSD applying the method. The method comprises the steps of acquiring working temperature information of the SSD at the moment of outage; acquiring current external temperature information; searching data disappearance time information corresponding to the current external temperature information and the working temperature information from a corresponding relationship among the external temperature information, the working temperature information and the data disappearancetime information according to the current external temperature information and the working temperature information; and performing read-write operation according to the data disappearance time information. The method has the effect that the data do not easily disappear.

Description

technical field [0001] The present invention relates to the technical field of data storage, in particular to an SSD data loss prevention method, system and SSD applying the method. Background technique [0002] At present, Solid State Drive (Solid State Drive), commonly known as solid state hard disk, solid state hard disk is a hard disk made of solid state electronic memory chip array, because the solid capacitor is called Solid in Taiwan, China. SSD is composed of control unit and storage unit (FLASH chip, DRAM chip). [0003] Currently, in a single level cell (SLC, single level cell) flash memory device, one transistor can accommodate 1 bit of data. Data is written into the cell through the passage of electrons; apply a high enough voltage across them to create an electric field strong enough that electrons will penetrate the oxide and enter the floating gate. Remove the voltage and the electrons will remain in the floating gate. Put a voltage across the channel witho...
