Executive Summary

As system bandwidths continue to increase, memory technologies have been optimized for higher speeds and performance. The next generation family of Double Data Rate (DDR) RAMs are DDR3 RAM. DDR3 RAMs offer numerous advantages compared to DDR2. These devices are lower power, they operate at higher speeds, offer higher performance (2x the bandwidth), and come in larger densities. DDR3 memory devices provide a 30% reduction in power consumption compared to DDR2, primarily due to smaller die sizes and the lower supply voltage (1.5V for DDR3 vs. 1.8V for DDR2). This paper represents the overall design and architecture of Low power Double Data Rate 3(DDR3) memory controller. In this paper clock gating is used as a low power technique .
