AI Technical Summary

Technical Problem

Existing data storage devices are vulnerable to physical attacks where attackers can read the contents of memory cells using needles or probes, compromising data security.

Method used

A data storage device with a multilayer arrangement of connecting elements is designed such that removing a first layer of connecting elements interrupts the connection, while a second layer remains, making it difficult for attackers to operate the memory cells, and includes additional lines to segment the array into isolated areas.

Benefits of technology

The solution significantly impedes unauthorized access and operation of memory cells, rendering physical attacks unattractive by ensuring the connection is interrupted upon removal of the outer layer, maintaining functionality in isolated areas.

Abstract

Data storage comprehensive: a memory cell arrangement (12) with a plurality of planar memory cells; a multi-layered arrangement (13) of access lines (14, 15) that provides a connection between the plurality of memory cells and that at least partially overlaps with the memory cell arrangement (12); wherein the multilayer arrangement (13) of access lines (14, 15) is designed such that when a first layer (161) of access lines (14) is removed while a second layer (162) of access lines (15) arranged between the first layer (161) and the memory cell arrangement (12) remains, at least one connection is interrupted;
