Lead
Mehr als von Neumann Rechner - Materialien und Integrierte 3-Dimensionale gestapelte Multiterminale Memristive Oxide Speicher und Logiken zum Ersetzen von Transistoren für Neuromorphes Rechnen
Lay summary

Heutzutage werden die meisten Speicherbauteile in der Informationstechnologie als Singuläre Binäre Adressen behandelt auf welche binäre Null und Eins Codes geschrieben werden können. In dieser Forschungsarbeit, bauen wir erste Materialien und Speicherlogiken die auf seriellen Verknüpfungen von sogennanten Memristiven Speichern bestehen und untersuchuchen das Codieren von nicht Binärer Information für die Zukunft. Hierzu werden neue Materialkonzepte untersucht als mögliche Speicher- und Logikbauteile für Computerhardware der Zukunft.

Abstract

Till date, research driven by electric engineers has considered only addressing single memristor elements one-by-one in cross-bar arrays being all of the same material constituents. As a new field of research, we aim to create and understand series and anti-series connected memristors based on bipolar oxide elements for logic applications on the basis of purely ionic and electronic conductors. The establishment of engineering guidelines and models for material selection, manufacturing and programming of "multiple-resistive states" for multi-bit memristive connected elements for higher logics is the cornerstone of the suggested research. Technologically it is the prerequisite to define higher neuromorphic computing architectures and logics by tuning the memristive programmable voltages and slopes over a broader range. The key innovative ideas are the following: Serial and anti-serial pair connections of bipolar oxide-memristors operating on ONE dominant type of carrier (oxygen anionic or electronic p- or n-type) are designed. Through the choice in oxide and metal-oxide Schottky barrier the polarity of each serial element can be tuned to be either clock- or anti-clock-wise to define serial or anti-serial pair bits to steer the net memristance and addressable number of resistance states to more than binary. This is a powerful approach to gain high volumes of multiple-resistance states to be addressed for Boolean logic operations for future implementation as hardware components in neuromorphic computing. In the second part of the proposal, a classic 2-terminal fabrication and address new concepts for memristors to a 3-terminal geometry of bipolar thin film oxides is altered and elucidate the role of interfaces. As a high risk/high grain part higher serial 3-terminal memristor connected architectures are targeted, and the materials and memristive variables for future logics to-be-defined. This will enable new memristor/CMOS logic concepts beyond 2-terminal units. Through this proposal we advance from understanding single standard oxide-based bipolar memristive memory elements to multi-bit connections of memristive elements with selective functions for logics.
