A high-reliability universal solid state disk rapid physical destruction circuit and method

Abstract

The invention discloses a high-reliability universal solid state disk rapid physical destruction circuit and method, and belongs to the technical field of electronics. The circuit comprises a DC module and a FLASH array, and is characterized by further comprising an input power limiting module, a direct-current voltage conversion module, a self-destruction control module and a switch tube, whereinthe input power limiting module and the direct current voltage conversion module are arranged in parallel; the direct current voltage conversion module, the self-destruction control module and the switch tube are electrically connected in sequence; and the switch tube is electrically connected with the FLASH array. The circuit design is simple, the number of peripheral elements is small, the sizeis small, the destruction time is controllable, and the destruction rate is high; the circuit and the method can solve the problems that a self-destruction circuit in the prior art is too large in size, the self-destruction time is long, the input power is large, the self-destruction is incomplete, a self-destruction circuit is too complex, and the reliability is low, and become a universal physical destruction circuit and method suitable for solid state disks of various environmental conditions and various mainstream standard sizes, and meet the confidentiality requirement of the national defense industry, the finance industry and other industries for data safety.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a high-reliability general-purpose solid-state hard disk rapid physical destruction circuit and method. Background technique [0002] With the rapid development of information technology, the total amount of global data continues to increase. Calculated according to the current annual growth rate of 50%, by 2020, the total amount of global data will reach 40ZB, and the total amount of data in my country will reach 8.6ZB, accounting for about 21% of the world. In this context, solid-state drives have been widely used as data carriers because of their ultra-high data throughput rate and large capacity, but the accompanying data security issues have become increasingly prominent. [0003] Soft destruction and physical destruction are two effective measures to protect the data security of solid-state drives under special circumstances. They are commonly used in the f...
