In this paper, recent progress of phase change memory (PCM) is reviewed. The electrical and thermal properties materials are surveyed with a focus on the scalability their impact device design. Innovations in structure, cell selector, strategies for achieving multibit operation 3-D, multilayer high-density arrays described. scaling PCM illustrated experimental results using special test structures novel material synthesis. Factors affecting reliability discussed.
Cross-point memory architecture offers high device density, yet it suffers from substantial sneak path leakages, which result in large power dissipation and a small sensing margin. The parasitic resistance associated with the interconnects further degrades output signal imposes an additional limitation on maximum allowable array size. In this paper, we study requirements of resistive cross-point under worst-case write read operations. We focus data pattern dependence compare effect cell...
In this paper, we employed Ramen spectroscopy to monitor oxygen movement at the electrode/oxide interface by inserting single-layer graphene (SLG). Raman area mapping and single-point measurements show noticeable changes in D-band, G-band, 2D-band signals of SLG during consecutive electrical programming repeated for nine cycles. addition, inserted enables reduction RESET current 22 times power consumption 47 times. Collectively, our results that monitoring a resistive random access memory...
China is accelerating green and low-carbon transformations of cultivated land to achieve a carbon peak by 2030 actively respond global climate change. Evaluating the use efficiency (CLUE) determining its driving factors help reduce land-use emissions promote land. However, previous emission-based studies CLUE have been insufficient.
