Solid state disk with power-down protection and physical destruction functions

Abstract

The invention discloses a solid state disk with power-down protection and physical destruction functions. The solid state disk with power-down protection and physical destruction functions includes asolid state disk, wherein the solid state disk is internally composed of a main control chip, a flash memory array, a power supply system, a destruction control module and an energy storage unit; theenergy storage unit uses a plurality of large-capacity electrolytic capacitors in parallel connection to store energy for the destroying circuit to use, and short-time power supply is provided at themoment of power down of the solid state disk; and the power supply system is composed of a boosting and charging and discharging circuit, a power supply changeover switch, an energy storage unit, a power down detection module, a power supply management unit and a destroying trigger switch. According to the invention, the specially designed circuit is added in the compact space of the solid state disk; and meanwhile, two requirements of data integrity protection and hard disk data irreversible physical destruction under an abnormal power failure condition are met, and the functionality and thesafety of the solid state disk are improved, and the number of components in the solid state disk is greatly reduced through multiplexing of the energy storage element, and the internal space of the solid state disk is saved.

Description

technical field [0001] The invention relates to the technical field of computer solid-state hard drives, in particular to a solid-state hard drive with power-down protection and physical destruction functions. Background technique [0002] Solid-state hard disk, referred to as solid-state disk, is a hard disk made of solid-state electronic storage chip arrays, which is composed of a control unit and a storage unit. The shape and size of the product are also completely consistent with the traditional hard disk, but the I / O performance is greatly improved compared with the traditional hard disk. It is widely used in military, vehicle, industrial control, video surveillance, network monitoring, network terminal, electric power, medical, aviation, Navigation equipment and other fields. [0003] In computer applications, the data stored in the computer is very important. In some special applications, abnormal power failure of the computer system is inevitable or even frequent. ...
