从系统设计观点来看,理想的半导体存贮器对于设计来说既要容量大,又要速度快,既要灵活性强,又要使用简单,同时还要功耗低。但是,直到现在还没有一种完美的器件能完全满足上述要求。 非易失性半导体存贮器的诞生,使人们看到一条实现理想要求的存贮器的最好途径。多年来,人们做了很大的努力,致力于这方面的研制,并已取得了不少成果。 From the system design point of view, the ideal semiconductor memory for the design of both capacity and speed, it is necessary flexibility, but also easy to use, but also low power consumption. However, until now there is no perfect device to fully meet the above requirements. The birth of non-volatile semiconductor memory, so that people see the best way to achieve the desired memory requirements. Over the years, people have made great efforts to devote themselves to the research and development in this field and have achieved quite a lot.
