Abstract

The utility model relates to a solid state disk with a rapid data destruction function, and belongs to the technical field of rapid data destruction in solid state storage. According to the utility model, data destruction of the solid state disk is carried out by two destruction modes of data soft destruction and data hard destruction, wherein the process of the data soft destruction is as follows: a trigger switch applies a low-level pulse signal, and destructs data in a hard disk controller so as to format the stored content; the process of the data hard destruction is that performances of a stored medium are destructed by a mode of applying high pressure to a FLASH by a power supply conversion chip so as to destruct data. The two destruction modes are matched mutually so as to achieve the function of rapid data destruction and eliminate the safety hazard of key data. The solid state disk with the rapid data destruction function, which is provided by the utility model, is rapid in destruction speed, is simple to operate, and lowers the cost of the solid state disk greatly.

Embodiment

For making the purpose of this utility model, content and advantage clearer, below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.

As shown in Figure 1, Figure 2 and Figure 3, the utility model provides a kind of and has certainly destroyed the solid state hard disc of function with rapid data, comprise: the first trigger switch 1, the second trigger switch 2, the first D-type latch 3, the second D-type latch 4, hard disk controller 5, SATA22P clamping plate connector 6, not gate 7, with door 8, power conversion chip 9 and storage chip 10, described storage chip 10 is FLASH chip; Described the first trigger switch 1 is electrically connected to the first D-type latch 3, and the first D-type latch 3 is electrically connected to hard disk controller 5 and SATA22P clamping plate connector 6 respectively, and described hard disk controller 5 is electrically connected to storage chip 10;

Described the first D-type latch 3 is connected with the D17 pin of hard disk controller 5, is connected with the P13 pin of SATA22P clamping plate connector 6.Described the second D-type latch 3 is connected with P13 pin and the P15 pin of SATA22P clamping plate connector 6 respectively.As shown in Figure 4, P13 and the P15 pin of SATA22P clamping plate connector 6 are open ports, for self-defined, in the utility model, this are defined as to data destroying pin.
