随着信息大爆炸时代的到来,要求存储器在单位体积中能够存储更多的信息,然而在缩减器件尺寸上会遇到摩尔定律失效的瓶颈.为克服这个技术上的限制,使用一些功能性材料用于存储器成为研究热点.介绍3大类功能材料的非易失性存储器,指出多金属氧酸盐基存储器,具有很强的电子接收能力和实现分子级存储的潜力; 金属纳米粒子存储器,因离散的金纳米粒子功能层有提升器件性能和利于实现存储性能实时可控,所以在当今先进存储器研究领域受到广泛关注; 生物材料基存储器,因特定的生物材料能发生可逆电阻开关现象,且原料具有可持续获得性和自降解性等优点,也成为存储器研究领域的明星.文章客观讨论了这3类材料用于存储器上的不足.

With the advent of the era of information explosion, memory is required to store more information in unit volume. However, people encounter the bottleneck of Moore's Law failure in reducing device size. In order to overcome the theoretical limitation, the use of some functional materials for memory has become a research hotspot. This paper outlines the non-volatile memory based on three types of functional materials: Polyoxometalates(POMs)-based memory, in which POMs have strong electronic reception capability and potential for molecular-level storage; Metal nanoparticles-based memory which has attracted much attention in the field of advanced memory as well, due to its advantages of improving device performance and realizing real-time controllable storage; Biomaterial-based memory, which is another rising-star material used in the field of memory research because special biomaterials have reversible resistance switching, together with a series of other advantages such as sustainable availability of raw materials, self-degradation and so on. This review also discusses the shortcomings of these three types of materials used in memory devices.
