Magnetic random access memory based on magnetic tunnel junctions (MTJs) is among the most attractive technologies of emerging nonvolatile memories. However, the integration of spin-based devices in integrated circuits is still hindered by a lack of established standard electrical simulator models. Many of such models have been proposed during the past decade which can be classified into two categories:...
Am-IDGFET is a new family of particular devices in view of the fact that it associates three benefits: (i) it is usually a 1-D electronic device (CNT or SiNW), meaning high mobility, achievable current density and high I ON /I OFF ratio; (ii) Independently controlled gates which offers the device extra logic options; (iii) ambipolar behaviour opens the way for N- and P-type polarities...
The combination of non-volatility, fast access time and endurance in MRAM technology paves the path toward an universal memory. Although an expanding attention is given to two-terminal Magnetic Tunnel Junctions (MTJ) based on Spin-Transfer Torque (STT) switching as the potential candidate for future memories, its reliability is significantly decreased because of the common writing/reading path. Three-terminal...
In this paper, we exploit the ambipolarity property of double gate devices such as DG-CNTFETs to design a new 4:1 multiplexer, with a significant reduction in circuit complexity with respect to conventional CMOS-based multiplexers for equivalent functionality. Based on Pass-Transistor Logic, it demonstrates performance improvement of up to 3× concerning Power-Delay-Product reduction, as compared to...
A novel Ambipolar Binary Decision Diagram (Am-BDD) is proposed in this paper, to adapt this logic synthesis and verification technique to logic built with ambipolar devices. We demonstrate how this method enables us to build DG-CNTFET-based n-input reconfigurable cells based on pass-transistor-logic obtained from Am-BDDs. We also show how specific correlations between configuration signals can lead...
Novel devices based on carbon nanotube field effect transistors demonstrate lower power consumption over conventional CMOS technologies. In this paper, we focus on socalled matrix-based nanocomputer architectures that combine low power and routing overheads of cell matrices with flexibility of FPGAs. We introduce a new interconnect topology for cell matrices that provides the flexible logic depth...
The back-gate terminal on double-gate ambipolar transistors can be used as a powerful vector to achieve fine-grain logic reconfigurability. This paper describes ways of exploiting this property to improve on standard cell logic techniques, and to build logic gates with tunable functionalities. Given the vastly reduced transistor count, conventional use of reconfigurable interconnect at the cell level...
This paper presents a set of circuit design approaches to achieve clocked standard logic cell functions with ambipolar double-gate devices such as the Double Gate Carbon Nanotube FET (DG-CNTFET). The cells presented in this work use the infield controllability of the device to reduce transistor count over conventional standard cells by only requiring n+1 transistors (where n is the fan-in), and achieve...
DRDC Valcartier has initiated, through a PRECARN partnership project, the development of an advanced simulation test bed called CanCoastWatch. The main focus of this test bed is to study net-enabled concepts such as distributed information fusion algorithms and architectures, dynamic resources and networks configuration management, and self-synchronising units and agents. The test bed allows the evaluation...
This paper proposes an automated learning method (ALM) based on real-coded genetic algorithm (RCGA) to infer the multi-criteria classifiers (MCC) parameters. The multi-criteria classifiers (or multi-criteria classification methods) considered are based on concordance and discordance concepts. A military database of 2545 forward looking infra-red (FLIR) images representing eight different classes of...
This paper reviews multiple criteria classification methods (or multi-criteria classifiers), particularly those based on concordance/discordance concepts. The concordance refers to an aggregated metric indicating the truthfulness of a proposition according to a coalition of criteria. The discordance is an aggregated metric representing the strength of the opposition coalition to the truthfulness of...
