Abstract (in Japanese) (See Japanese page) 
(in English) A dynamic SDRAM-mode-control scheme for low-power systems was developed and tested. The scheme is based on two dynamic changes of SDRAM modes: from active standby to standby and from standby to active standby. It reduces both the operating current and the latency of an SDRAM. An analysis using benchmark programs shows that the developed scheme reduces the SDRAM operating current by 40% and latency by 38% compared to those in standby mode. An SDRAM controller based on this scheme and 0.18-um CMOS technology was developed. The area of the controller is 0.28mm2, and its operating current is 2.5mA at 1.8V and 100 MHz.
