Memory Technologies for Mobile Era

For last three decades, semiconductor memory business has greatly grown due to the tremendous progress of electronic data processing (EDP) mainly led by outstanding evolution of PC technology. Recently, various mobile appliances such as hand-held phone, DCS, and MP3 drive new growth of semiconductor memory, which results in unprecedented demand of non-volatile memories, especially mass storage NAND flash. The mobile appliances which aim for smaller and lighter products while improving the performance under ever-increased demand of longer battery lifetime impose different requirements on the semiconductor memories. The newly defined requirements along with short life cycle and customer orientation of mobile products transform the memory semiconductor from standard data storage memory to diverse solution memory. It is predicted that this trend is magnified in the future memory market. In this paper, discussion about the technology trend of memory semiconductor in the mobile era and also the memory technology required satisfying the mobile appliances
