Resistive switching (RS) based on the formation and rupture of conductive filament (CF) is promising in novel memory and logic device applications. Understanding the physics of RS and the nature of CF is of utmost importance to control the performance, variability and reliability of resistive switching memory (RRAM). Here, the RESET switching of HfO2-based RRAM was statistically investigated in...

This paper presents a novel Fuzzy Multiple Reference Model Adaptive Controller (FMRMAC) for systems that are multi modal in nature and show scheduled ‘Jumps’ in their operation. The proposed scheme incorporates a fuzzy logic switching method in the Model Reference Adaptive Control (MRAC) framework without any explicit identifier. The fuzzy switching scheme produces a ‘soft’ way of model generat...

The objective of this paper is to explore the applicability of a very specific design technique at a gate-level to achieve a reduction of switching noise in conventional CMOS digital circuits. The proposed technique optimizes switching noise maintaining operation speed, power consumption and transistor count. Basically, we will show how the selection of the suited pin in a gate for implementing...

In contrast to the previous ARM microprocessor, the ARM Cortex-M3 processor provides a method for accelerating context switching, which is supported by dedicated hardware logic vis a software interrupt (or trap). In general, it is expected that retaining the context of a task using hardware will reduce the context switching time, but it is also known that software interrupts or traps incur thei...

This paper deals with the direct torque control (DTC) of the induction motor. This type of control allows decoupling control between the flux and the torque without the need for a transformation of coordinates. However, as with other hysteresisbased systems, the classical DTC scheme represents a high ripple, in both the electromagnetic torque and the stator flux and a distortion in the stator c...

The steady-state operation of maintaining voltage stability is done by switching various controllers scattered all over the power network. When a contingency occurs, whether forced or unforced, the dispatcher is to alleviate the problem in a minimum time, cost, and effort. Persistent problem may lead to blackout. The dispatcher is to have the appropriate switching of controllers in terms of typ...

This paper focuses on discrete-time sliding mode control with SIIM fuzzy adaptive switching gain. The adaptive switching gain is calculated using the simplified indirect inference fuzzy logic. Two fuzzy inputs are the normal distance from the present state trajectory to the switching function and the distance from the present state trajectory to the equilibrium state. The fuzzy output ( ) out f...

Abstract We have investigated the spin-Hall effect (SHE)-assisted spin transfer torque (STT) switching mechanism in a three-terminal MTJ device developed using p-MTJ (perpendicular magnetic tunnel junction) and heavy metal materials of high atomic number, which possesses large spin–orbit interaction. Using schematic complementary-metal-oxide-semiconductor (CMOS) logic, we designed three basic h...

Spin orbit torque (SOT) has been considered as one of the promising technologies for next-generation magnetic random access memory (MRAM). So far, SOT widely utilized inducing various modes magnetization switching. However, it is challenging to integrate multiple switching together. In this work we propose a method implementing both unipolar and bipolar perpendicular within single device. The m...
