Abstract(in English) This paper describes amulti giga bit DRAM technologies focused on circuit design. Process and device technique less than 0.15um induce some kind of problems to achieve high performance DRAM. To solve these problems, key circuits design technique have been introduced as follows. Sense amplifire circuits and low Vth transistor logic with power management are useful for high spped at low voltage. Long data retaintion cuircuit technique good for mobile equipments is required. Additionally, testability, redundancy and new device structure DRAM are presented. These circuit technologies will provide not only multi giga bit DRAM but also multi media system LSI near future.
