The development of a practical magnetic tunneling junction (MTJ) ten years ago allowed the creation of a new class of non-volatile memories. This technology may offer superior resistance to total ionizing dose and virtually unlimited write endurance, making it more attractive than flash memories for space applications. Although a number of manufacturers are developing high-density bulk magnetic...

Using the degeneration formula for Doanldson-Thomas invariants, we proved formulae for blowing up a point and simple flops.

We study flops of Calabi-Yau threefolds realised as Kähler-favourable complete intersections in products projective spaces (CICYs) and identify two different types. The existence the type can be recognised from configuration matrix CICY, which also allows for constructing such examples. first corresponds to rows containing only 1s 0s, while second a single entry 2, followed by 0s. give explicit...

Reversible logic has come to the forefront of theoretical and applied research today. Although many researchers are investigating techniques to synthesize reversible combinational logic, there is little work in the area of sequential reversible logic. Latches and flip-flops are the most significant memory elements for the forthcoming sequential memory elements. In this paper, we proposed two ne...

Contention-less flip-flops (CLFF’s) and separated power supply voltages (VDD) between flip-flops (FF’s) and combinational logics are proposed to achieve a maximum energy efficiency operation. The proposed technologies were applied to a 16-bit integer unit (IU) for media processing in a 65-nm CMOS process. Measurement results of fabricated chips show that the proposed CLFF reduces the minimum op...

Abstract – Presented below is an interesting type of associative memory called toggle memory based on the concept of T flip flops, as opposed to D flip flops. Toggle memory supports both reversible programming and charge recovery. Circuits designed using the principles delineated below permit matchlines to charge and discharge with near zero energy dissipation. The resulting lethargy is compens...

In this paper, simple circuital techniques to design efficient pulse triggered flip-flops are presented. The proposed approach aims at considerably alleviating the detrimental effects of current contention mechanisms, occurring at critical switching nodes of the circuits. In this way, both latency and power consumption of pulse triggered flip-flops are reduced. The proposed approach is assessed...

Energy consumption has become one of the important factors in digital systems, because of the requirement to dissipate this energy in high-density circuits and to extend the battery life in portable systems such as devices with wireless communication capabilities. Flip-flops are one of the most energyconsuming components of digital circuits. This paper presents techniques to reduce energy consu...
