Anordnung zum Speichern von Daten und Verfahren und Vorrichtung zum Lesen der Daten

摘要

Substrate has n lines and m columns of conductor paths (4,5) insulated from each other at crossing points (6). Electric connecting paths (10) assigned to crossing points are formed as part of rub-off layer applied on substrate so they (10) can be destroyed by pressure to interrupt electric connection between crossing conductors. To read data voltage is applied to each row to detect if connection has been rubbed off. Independent claim is included for 1) procedure to read data on device by applying voltage to each row in sequence with other n-1 paths are connected to earth with CPU used to create connections between n path and voltage source and n-1 paths and earth.
