The solid state disk power-fail protection method and device of the interface judges whether the working state of the main power supply is normal work, normal shutdown or abnormal power-fail by setting threshold voltages for the main power supply and the built-in static power supply and detecting in real time, the standby power supply is started to supply power to the solid state disk only after the main power supply is confirmed to be abnormally powered down, and when the main power supply is detected to be normally powered down, the standby power supply is not required to be opened to supply power, so that frequent charging and discharging of the standby power supply are avoided, electric energy is saved, and meanwhile, the service life of the standby power supply is protected.
Description
Technical field
The present invention relates to a kind of computing machine solid-state storage field, particularly a kind of power-off protection of solid state disk method and device based on the PCIE interface.
Background technology
Power down protection is meant when the normal power supply power supply power-fail, is the memory device power supply through standby power supply rapidly, can not lose in the data of a period of time internal memory devices guaranteeing, when primary power is replied power supply, automatically switches to the primary power power supply again.
For solid state hard disc; Need the data of power down protection to write data often; The system that data is had high reliability request needs to use uninterrupted power source (Uninterruptible Power Supply detects UPS) to continue as system's power supply behind the primary power powered-off fault.For example, be the power supply of Memory Controller Hub and Nonvolatile memory by standby power supply behind the primary power powered-off fault, thereby avoid internal storage data to lose.
In the prior art; One Chinese patent application 201010180476.X disclosure of the Invention a kind of power-off protection of solid state disk method and device; This method comprises: detect the solid state hard disc power down, and to switch in advance the energy storage device that is provided with by working power be the solid state hard disc power supply; During energy storage device was the solid state hard disc power supply, the data that solid state hard disc being is is being read and write were saved in hard disk; Detect working power and restore electricity, and to switch to working power by energy storage device be solid state hard disc power supply.
One Chinese patent application number 200910091174.2 disclosure of the Invention another kind of power-off protection of solid state disk method, Apparatus and system, comprising: the self-discharge time of obtaining first super-capacitor module; When said self-discharge time during less than preset value, send second super capacitor and be discharged to charge-discharge circuit to connect the second super module discharge loop, be the solid state hard disc power supply by second super-capacitor module.
