Well known Moore's Law shows, number of transistors would be double in every 1.5 years. It is still accurate Jitting for logics after the quarter century history of Integrated Circuit industry, so it might be a kind of Semiconductor Bible. However, even in CMOS logic process, it is getting difficult to achieve it because of device scalability, getting larger leakage current and parasitic resistance/capacitance. In the memory processes, Memory has recently slower integration growth than ever as well as comparing with CMOS process because of complicated cell structure, consequently twofold density increase in every two years. As mentioned in this paper, memory application area get increased over the classical main memory application of computer. To provide memory density that follows Moore's Law, Fab. oriented development activity is not sufficient. Packaging technology is expected to take part in important role to increase memory growth rate. Mobile application is pretty new area that grows very fast, and requires small form factor but high density from various memory types.
