Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Example 1
Fig. 1 is a schematic structural diagram of a destruction device for a solid-state hard disk according to an embodiment of the present invention.
In this embodiment, the solid state disk comprises a plurality of memory granules 1.
As shown in fig. 1, the destruction apparatus 100 for a solid state disk includes a power supply interface 10, a control circuit 20, a driving circuit 30, and a voltage detection circuit 40.
Referring to fig. 1, the voltage detection circuit 40 is respectively connected to the power supply interface 10 and the control circuit 20, and is configured to output a destruction signal to the control circuit 20 when detecting that the external power supply is connected to the power supply interface 10 and detecting that the voltage output by the external power supply is a normal destruction voltage. A first terminal of the driver circuit 30 is connected to the power supply interface 10 and a second terminal of the driver circuit 30 is connected to the one or more memory particles 2. The control circuit 20 is connected to the control end of the driving circuit 30, and is configured to output an enable signal to the driving circuit 30 when receiving the destruction signal, so as to inject a destruction current into the storage particles 1 connected to the driving circuit 30 through the driving circuit 30, and destroy the corresponding storage particles 1.
Wherein, the normal destruction voltage can be 28V.
Specifically, referring to fig. 1, when the voltage detection circuit 40 detects that the external power source is connected to the power supply interface 10, if the voltage output by the external power source, for example, 12V, is lower than the normal destruction voltage, for example, 28V, the control circuit 20 cannot detect the destruction signal, and the destruction is in a stop state; if the voltage output by the external power supply is a normal destruction voltage, such as 28V, the control circuit 20 detects the destruction signal output by the voltage detection circuit 40, outputs an enable signal to enable the driving circuit 30 to operate, and injects destruction current into each storage particle 1 connected to the driving circuit 30 to destroy the corresponding storage particle.
The destruction device of the solid state disk can thoroughly destroy the storage particles from the physical layer, and prevent confidential data in the solid state disk from being recovered and stolen; the method can prevent the misoperation of low voltage, and cannot start the destruction program when the input voltage is lower than the normal destruction voltage; one or more storage particles can be destroyed at the same time, and the operation process is simple.
As one example, the power supply interface 10 may be connected to an external power supply through a SATA (Serial Advanced technology attachment) connector.
Specifically, the destruction device 100 is integrated in the solid state disk, and is connected to an external main control board including an external power supply through a SATA connector. When the external power supply inputs a normal destruction voltage and enters the solid state disk through the SATA connector, the destruction device 100 starts to operate. Under the action of the voltage detection circuit 40 and the control circuit 20, the normal destruction voltage is introduced to the power supply pin of the corresponding storage particle 1 through the driving circuit 30, and under the action of the strong current, the corresponding storage particle 1 is physically destroyed.
As an example, the driving circuit 30 includes a MOS transistor, a control terminal of the MOS transistor is connected to the control circuit 20, a first terminal of the MOS transistor is connected to the power supply interface 10, and a second terminal of the MOS transistor is connected to the one or more storage particles 1.
Specifically, when the control circuit 20 outputs an enable signal to the control terminal of the MOS transistor, the MOS transistor is turned on, and the voltage provided by the external power supply can be directly supplied to the corresponding storage particle 1, so that the corresponding storage particle 1 is physically destroyed by the strong current.
As an example, as shown in fig. 2, the destruction device 100 further includes: a built-in power supply 50 and a first power switch 60. The built-in power supply 50 may be a power supply built in the solid state disk, and the power supply voltage of the built-in power supply 50 may be 3.3V.
Referring to fig. 2, a first terminal of the first power switch 60 is connected to the built-in power supply 50, and a second terminal of the first power switch 60 is connected to the control circuit 20 and the power supply terminals of the respective memory particles 1, respectively, wherein a user turns on the first power switch 60 to power on the control circuit 20 and the respective memory particles 1.
As an example, as shown in fig. 3, the destruction device 100 further includes: a voltage dropping circuit 70 and a second power switch 80.
Referring to fig. 2, a first end of the voltage-reducing circuit 70 is connected to the power supply interface 10, and the voltage-reducing circuit 70 is configured to reduce a voltage output by an external power source when the external power source is connected to the power supply interface 10. A first end of the second power switch 80 is connected to a second end of the voltage-reducing circuit 70, and a second end of the second power switch 70 is connected to the control circuit 20 and the power supply end of each storage particle 1, wherein when an external power source is connected to the power supply interface 10, a user turns on the second power switch 80, so that the control circuit 20 and each storage particle 1 are powered on.
As an example, the destruction device 100 may include both the built-in power supply 50 and the voltage reduction circuit 70, and the first power switch 60 and the second power switch 80 may be the same power switch, so that the reliability and stability of the power supply of the solid state disk can be ensured.
In this example, the built-in power supply 50 may be a rechargeable battery, and when the external power supply is connected to the power supply interface 10, the external power supply may charge the built-in power supply 50 through the voltage reduction circuit 70.
As an example, as shown in fig. 4, the control unit 20 is further connected to each storage particle 1, and is configured to obtain a feedback voltage of each storage particle 1, and obtain a destruction state of each storage particle 1 according to the feedback voltage.
In this example, the control circuit 20 may have a power-off destruction incomplete secondary power-on re-destruction function. Specifically, for the uncontrollable factors of the environment, the external power source is suddenly powered off, the destruction behavior of the storage particles 1 being executed is finally interrupted, and if the storage particles 1 are not completely destroyed, when the external power source is started to return to normal, the control circuit 20 can physically destroy the storage particles again, thereby ensuring the reliability and stability of the destruction.
