  • Efficient 16 Boolean Logic and arithmetic based on bipolar oxide memristors
    Science China Information Sciences, 2020
    Co-Authors: Rui Yuan, Teng Zhang, Ru Huang, Zhenhua Zhu, Qingxi Duan, Yu Zhu, Yu Wang, Yuchao Yang
    Abstract:

    The physically separated memory and Logic units in traditional von Neumann computers place essential limits on the performance and cause increased energy consumption, and hence in-memory computing is required to overcome this bottleneck. Here, a new bipolar memristor based in-memory Logic approach is proposed, which is capable of achieving all 16 possible Boolean Logic functions in a single device in less than 3 steps. This approach does not require initialization and can facilitate Logic cascading, and the calculation taking place in-situ is showcased by 1-bit full adder and 2-bit multiplier with improved efficiency, thus showing a great prospect in future in-memory computing architecture.

  • Multifunctional Nanoionic Devices Enabling Simultaneous Heterosynaptic Plasticity and Efficient In-Memory Boolean Logic
    Advanced Electronic Materials, 2017
    Co-Authors: Yuchao Yang, Minghui Yin, Zongwei Wang, Teng Zhang, Yimao Cai, Ru Huang
    Abstract:

    The development of smart, scalable, and power efficient computers relies on innovative technologies that can distribute memory alongside processing, such as emerging neuromorphic computing and in-memory Logic technologies. Here, a type of vertical 3-terminal oxide based nanoionic device capable of implementing heterosynaptic plasticity and nonvolatile Boolean Logic simultaneously is demonstrated. The heterosynaptic plasticity endows the devices with facilely tunable synaptic kinetics via tailoring modulatory signals, which is shown to be crucial for achieving optimized learning scheme, therefore offering promising building blocks for neuromorphic computing. Furthermore, it is demonstrated that these heterosynaptic devices can simultaneously be utilized to implement nonvolatile Boolean Logic with improved efficiency compared with existing approaches, therefore implying in-memory computing potentialities. The heterosynaptic devices with such multifunctionality thus hold great potential for next-generation non-von Neumann computing applications.

  • implementation of complete Boolean Logic functions in single spin orbit torque device
    AIP Advances, 2021
    Co-Authors: Yunchi Zhao, Guang Yang, Jianxin Shen, Shuang Gao, Jingyan Zhang, Haochang Lyu, Kui Jin, Shouguo Wang
    Abstract:

    All 16 Boolean Logic functions in a single Ta/CoFeB/MgO device with perpendicular magnetic anisotropy were experimentally demonstrated based on the spin–orbit torque (SOT) effect. Furthermore, by combining with the voltage-controlled magnetic anisotropy (VCMA) effect, a novel SOT-MTJ (magnetic tunnel junction) prototype device with the assistance of the VCMA effect was further designed to perform magnetic field-independent Logic operations. The numerical simulations were carried out, demonstrating the feasibility to realize all 16 Boolean Logic functions in a single three-terminal device by applying the bias voltage and current injection as input variables. This approach provides a potential way toward the application of energy efficient spin-based Logic, which is beyond the current von Neumann computing architecture.

  • Implementation of Complete Boolean Logic Functions in Single Complementary Resistive Switch
    Scientific reports, 2015
    Co-Authors: Shuang Gao, Fei Zeng, Minjuan Wang, Guangyue Wang, Cheng Song, Feng Pan
    Abstract:

    The unique complementary switching behaviour of complementary resistive switches (CRSs) makes them very attractive for Logic applications. The implementation of complete Boolean Logic functions in a single CRS cell is certainly an extremely important step towards the commercialisation of related Logic circuits, but it has not been accomplished to date. Here, we report two methods for the implementation of complete Boolean Logic functions in a single CRS cell. The first method is based on the intrinsic switchable diode of a peculiar CRS cell that is composed of two anti-serial bipolar resistive switches with a rectifying high resistance state, while the second method is based directly on the complementary switching behaviour itself of any single CRS cell. The feasibilities of both methods have been theoretically predicted and then experimentally demonstrated on the basis of a Ta/Ta2O5/Pt/Ta2O5/Ta CRS cell. Therefore, these two methods—in particular the complementary switching behaviour itself-based method, which has natural immunity to the sneak-path issue of crossbar Logic circuits—are believed to be capable of significantly advancing both our understanding and commercialization of related Logic circuits. Moreover, peculiar CRS cells have been demonstrated to be feasible for tri-level storage, which can serve as an alternative method of realising ultra-high-density data storage.

  • Non-volatile spin switch for Boolean and non-Boolean Logic
    Applied Physics Letters, 2012
    Co-Authors: Supriyo Datta, Sayeef Salahuddin, Behtash Behin-aein
    Abstract:

    We show that the established physics of spin valves together with the recently discovered giant spin-Hall effect could be used to construct Read and Write units that can be integrated into a single spin switch with input-output isolation, gain and fan-out similar to complementary metal oxide semiconductor inverters, but with the information stored in nanomagnets making it non-volatile. Such spin switches could be interconnected, with no external amplification, just with passive circuit elements, to perform Logic operations. Moreover, since the digitization and storage occur naturally in the magnets, the voltages can be used to implement analog “weighting” for non-Boolean Logic.

  • Relational approach to Boolean Logic problems
    Lecture Notes in Computer Science, 2006
    Co-Authors: Rudolf Berghammer, Ulf Milanese
    Abstract:

    We present a method for specifying and implementing algorithms for Boolean Logic problems. It is formally grounded in relational algebra. Specifications are written in first-order set theory and then transformed systematically into relation-algebraic forms which can be executed directly in RELVIEW, a computer system for the manipulation of relations and relational programming. Our method yields programs that are correct by construction. It is illustrated by some examples.
