Abstract

The SDRAM requires the refreshing at every refresh time to maintain the data, and this operation consumes power. Because the power consumption of the processor is decreased, the power cosnumption on the SDRAM is taking large portion of the total power consumption. The refresh time can be expanded because the retention time and power consumption can be changed. In this paper we introduce the SDRAM controller which enables the analysis of the retention time for the power redectoin purpose.
