基于动态赋值的存储芯片产业颠覆性技术识别研究

Research on Identification of Disruptive Technologies in the Memory Chip Industry Based on Dynamic Assignment

为了探索存储芯片领域的颠覆性技术发展趋势,辅助产业各界精准把握技术机会,以Web of Science数据库和德温特专利数据库中存储芯片技术领域的论文和专利作为数据源,在LDA(Latent Dirichlet Allocation)模型技术主题筛选的基础上采用动态赋值法对6个技术指标进行综合评价,并结合数据解读和人工智慧识别出存储芯片领域颠覆性技术。研究结果表明,新型非易失性存储器技术中的可变电阻式存储器和相变化存储器、磁阻式随机存取存储器和仿生电子元器件及仿神经计算机可能成为存储芯片领域的颠覆性技术点。

In order to explore the development trend of disruptive technologies in thefield of memory chips and assist the industry to accurately grasp the technological opportunities,the papers of the Web of Science database and the patents of the Derwent patent database in the field of memory chip technologies are used as data sources,and the dynamic assignment method is used to comprehensively evaluate the six technical indicators based on the LDA model technology theme screening,andfinally combine data interpretation and Human intelligence identifies that in thefield of memory chips,variable resistive memory and phase change memory in the new non-volatile memory technology,magneto resistive random access memory,bionic electronic components and neural-like computers may become disruptive technology points in thisfield.
