re: Going green with DDR3 memory

This article caught my attention as it highlights the increasing power consumption challenges we face as we try to keep pace with society?s thirst for increased bandwidth. How the SoC accesses data from the DRAM has a significant impact on the total power consumption. The basic equation for power comprises three components: voltage, capacitance and frequency. While voltage and capacitance are addressed as ways to minimize power, we also see a key opportunity to reduce power by focusing on the operating frequency, without impacting bandwidth. For example, improving data throughput efficiency will improve data bandwidth for the same clock frequency. Therefore, if data throughput efficiency can be improved by 10%, the clock frequency can be reduced by 10% while still maintaining the same bandwidth, resulting in an estimated 10% reduction in dynamic power of the memory system. By thinking ?outside the box?, Virage Logic?s Intelli DDR3 offering uses this approach to deliver increased data throughput efficiency and reduced system level power, which when combined with the approaches in the article, make for a ?Greener? DDR3 system.
