Calculating memory system power for DDR3

DDR3 SDRAM provides additional bandwidth over previous DDR and DDR2 SDRAM. In addition to the premium performance, DDR3 has a lower operating voltage range. The result can be a higher bandwidth performing system while consuming equal or less system power. However, it is not always easy to determine the power consumption within a system application from the data sheet specification.

This technical note details how DDR3 SDRAM consumes power and provides the tools that system designers can use to estimate power consumption in any specific system. In addition to offering tools and techniques for calculating system power, Micron's DDR3-1067 "Data Sheet Specifications" on and a DDR3 Power Spreadsheet Usage Example are provided.
