Scientists from the All-Russian Scientific Research Institute of Experimental Physics (FSUE "RFNC-VNIIEF", a Rosatom enterprise) have developed a device for the rapid destruction of memory chips. The description of the patent for the invention is posted on the website of the Federal Service for Intellectual Property (Rospatent).
The invention is designed to protect information from unauthorized access by destroying the data carrier. The device is installed on the microcircuit and consists of a sealed housing with a pyrotechnic charge and an initiating element with current-carrying electrodes and a heating bridge. Applying an electrical signal to the electrodes causes the bridge to heat up, which leads to ignition of the charge. As a result, a large amount of gaseous combustion products are formed, which rupture the housing and destroy the microcircuit.
As indicated in the description, the effectiveness of the proposed scheme was experimentally confirmed. When prototypes are triggered, the strong disruptive effect caused by the dynamic formation of a large amount of gaseous combustion products of the working charge completely destroys the 1623RT1T, 1623RT2A, 1636RR4U and MT29F128G08AJAAAWP-IT:A memory chips. This guarantees the removal of the information recorded on them. At the same time, the electronic unit itself, which contains the information carrier, remains intact, since the area of impact is limited to its size.
