There is an increasing interest in developing Phase Change Memory (PCM) based main memory systems. In order to retain the latency benefits of DRAM, such systems typically have a small DRAM buffer as a part of the main memory. However, for these systems to be widely adopted, limitations of PCM such as low write endurance and expensive writes need to be addressed. In this paper, we propose PCMawa...

A new methodology for manipulating transient-amorphous states of phase-change memory (PCM) materials is reported as a viable means to boost the speed, yet reduce the power consumption of PC memories, and is applicable to new forms of PCM-based neuromorphic devices. Controlling multiple-pulse interactions with PC materials may provide an opportunity toward developing a new paradigm for ultra-fas...

Phase change memory (PCM) is the best candidate device among next generation random access memory technologies. PCM has a potential to replace Flash memory due to non-volatility and in-place programmability, and low power consumption. Even though lifetime of PCM is longer than flash memory, wear leveling is needed because of non-uniformity of storage workload or malicious attack. In this paper,...

Existing passive cooling solutions limit the short-term thermal output of systems, thereby either limiting instantaneous performance or requiring active cooling solutions. Active cooling requires relatively large amounts of power, and cannot easily and efficiently handle temperature spikes. PCMs (phase change materials) are materials that can change phase at a device’s operating temperature, ab...

The centrosomes in dividing cells follow a series of cyclical events of duplication and separation, which are tightly linked to the cell cycle. Serine/threonine-protein kinase NEK7 (NEK7) is a centrosomal kinase that is required for proper spindle formation during mitosis. In this study, we observed that centriole duplication was inhibited in NEK7-depleted cells. Ectopic expression of centrosom...

Integration of phase-change materials (PCMs) into building fabrics is considered to be one of the potential and effective ways of minimising energy-consumption and CO2-emissions in the building sector. In order to assess the thermal effectiveness of this concept, composite PCM drywall samples (i.e., randomly mixed and laminated PCM drywalls) have been evaluated in a model passive-solar building...

In this research work, nano-phase change material (NPCM) composites were prepared by adding 1 %, 2 and 3 % mass fractions of highly conductive carbon-based graphene nanoparticles into the base phase (PCM). The existence uniform dispersion in PCM was confirmed through Raman spectrometer scanning electron microscope (SEM) analysis. Fourier transform infrared (FTIR) x-Ray diffraction (XRD) results...
