Abstract
Description
Die Erfindung betrifft einen USB-Speicher-Stick mit einer ersten Einheit, welche mindestens einen Anschluss zum Anschließen an eine USB-Schnittstelle, einen Controller, einen ersten Datenspeicher und eine Notstromversorgung umfasst.The The invention relates to a USB memory stick having a first unit, which has at least one connection for connecting to a USB interface, a controller, a first data memory and an emergency power supply includes.
Ein
derartiger USB-Speicher-Stick ist als mobiler Datenträger
an sich bekannt und ersetzt gewöhnlich Disketten-, CD-
oder DVD-Speichermedien als Datenspeicher. Aufgrund dessen, dass
eine CPU eines Rechners, z. B. ein aus dem
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen USB-Speicher-Stick der eingangs genannten Art zu schaffen, welcher eine möglichst hohe Verfügbarkeit der im USB-Speicher-Stick hinterlegten Daten gewährleistet.Of the present invention is based on the object, a USB memory stick to create the type mentioned, which has the highest possible Availability of the data stored in the USB memory stick guaranteed.
Diese Aufgabe wird durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Maßnahmen gelöst.These The object is achieved by the characterizing part of the claim 1 measures resolved.
Vorteilhaft ist, dass ein derartiger USB-Speicher-Stick eine Spiegelung der Speicherinhalte der ersten und zweiten Einheit ermöglicht, wodurch der USB-Speicher-Stick für einen Einsatz in Echtzeitanwendungen geeignet ist. Das Zusammenwirken der Speicher erfolgt vorzugsweise mittels des an sich bekannten RAID(Redundant Array of Independent Disks)-Konzepts, wobei die Datenspiegelung mittels des spezifizierten RAID 1-Levels (RAID Level 1) verwirklicht ist.Advantageous is that such a USB memory stick a reflection of the Memory contents of the first and second unit allows making the USB memory stick suitable for use in real-time applications suitable is. The interaction of the memory is preferably carried out by means of the known RAID (Redundant Array of Independent Disks) concept, the data mirroring using the specified RAID 1 level (RAID level 1) is realized.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous embodiments of the invention will become apparent from the Dependent claims.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die einzige Figur der Zeichnung näher erläutert. Die Figur der Zeichnung zeigt in vereinfachter schematischer Darstellung Bestandteile eines USB-Speicher-Sticks.The Invention will be described below with reference to an embodiment with reference to the single figure of the drawing closer explained. The figure of the drawing shows in simplified form schematic representation Components of a USB memory stick.
