Sneak current issue of RRAM-based crossbar array is one of the biggest hindrances for high-density memory application. The integration of an addition selector to each cell is one of the most familiar solutions to avoid this undesired cross-talk issue, and resistive switching parameters would affect on the storage density. This paper investigates the potential impact of different resistive switching parameters on crossbar arrays with one-diode one-resistor (1D1R) and one-selector one-resistor (1S1R) architectures. Results indicate that 1S1R architecture is a more scalable technology for high-density crossbar array than 1D1R, and the storage density of 1D1R- and 1S1R-based crossbar array shows little dependence on resistance values of high-resistance state and low-resistance state, which gives a guideline for choosing appropriate selectors for RRAM crossbar array with specific parameters.
This article is to study the progressive impact of China’s fiscal policy on the sustainable development of the photovoltaic industry. On the one hand, the method based on characteristic facts, through the derivation of the evolutionary game theory of the two parties, finds the influence of the central and the local government on the alternate development of China’s photovoltaic industry production enterprises and power generation enterprises due to different policy subjects; on the other hand, from 2013 to 2018, the newly installed capacity of distributed photovoltaics in various provinces in China, through the method of measurement and empirical evidence, found that policy preferences (policy objects, methods, links, timing, and intensity) the effects of alternate development. This study believes that in terms of policy subjects, the central government should be the mainstay of the power generation, while in the production, considering the impact of the new crown epidemic and upstream raw materials, the joint efforts of the central and local governments are needed, and in terms of policy preferences, the Chinese government needs to give greater policy support to distributed photovoltaics in order to achieve carbon peaking in 2030 and carbon neutrality in 2060, which should not be interrupted by policies such as “whole county development” and “building surface photovoltaics.”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
