“…There are several proposed SPICE macromodels for the linear ion drift model [13], [22] and the nonlinear ion drift model [17]. A SPICE model for the Simmons tunneling barrier model has recently been proposed [21], but is complicated and inefficient in terms of computational time.…”

Abstract-Memristors are novel devices, which can be used in applications such as memory, logic, and neuromorphic systems. A memristor offers several advantages to existing applications: nonvolatility, good scalability, effectively no leakage current, and compatibility with CMOS technology, both electrically and in terms of manufacturing. Several models for memristors have been developed and are discussed in this paper. Digital applications such as memory and logic require a model that is highly nonlinear, simple for calculations, and sufficiently accurate. In this paper, a new memristor model is presented -TEAM, ThrEshold Adaptive Memristor model. Previously published models are compared in this paper to the proposed TEAM model. It is shown that the proposed model is reasonably accurate and computationally efficient, and is more appropriate for circuit simulation than previously published models.

“…There are a number of different models developed for the memristor in the literature [43,[47][48][49][50][51][52][53][54][55][56]. They differ in complexity and accuracy and we will cover some of them.…”

Moore's law has until today mostly relied on shrinkage of the size of the devices in integrated circuits. However, soon the granularity of the atoms will set a limit together with increased error probability of the devices. How can Moore's law continue in the future? To overcome the increased error rate, we need to introduce redundancy. Applying methods from biology may be a way forward, using some of the strategies that transforms an egg into a fetus, but with electronic cells.A redundant system is less sensitive to failing components. We define electronic clay as a massive redundancy system of interchangeable and unified subsystems. We show how a mean voter, which is simpler than a majority voter, impact a redundant system and how optimization can be formalized to minimize the impact of failing subsystems. The performance at given yield can be estimated with a first order model, without the need for MonteCarlo simulations. The methods are applied and verified on a redundant finite-impulse response filter.The elementary circuit behavior of the memristor, "the missing circuit element", is investigated for fundamental understanding and how it can be used in applications. Different available simulation models are presented and the linear drift model is simulated with Joglekar-Wolf and Biolek window functions. Driven by a sinusoidal current, the memristor is a frequency dependent component with a cut-off frequency. The memristor can be densely packed and used in structures that both stores and compute in the same circuit, as neurons do. Surrounding circuit has to affect (write) and react (read) to the memristor with the same two terminals.We looked at artificial neural network for pattern recognition, but also for self organization in electronic cell array. Finally we look at wireless sensor network and how such system can adopt to the environment. This is also a massive redundant clay-like system.Future electronic systems will be massively redundant and adaptive. Moore's law will continue, not based on shrinking device sizes, but on cheaper, numerous, unified and interchangeable subsystems.v

“…From the mathematical point of view, the ideal generic memristor is a memristor whose port and state equation can be converted via state variable transformation into a form that would correspond to (1), (2) or (3), (4). Among other things, it means that the ideal generic memristor and also the ideal memristor can be defined by the CR and PSM characteristics.…”
