It doesn't make sense to measure to DDR3 chip power, it is dynamic. 
You can get the DDR3 chip power from DDR3 datasheet, they are IDDx in
datasheet.

Subject: [SI-LIST] DDR3 Memory Power Measurement

Hi Experts,
I am trying to measure DDR3 total power consumption and needed some help.

The challenge is to measure only the power consumed by DDR3 excluding memory
controller. We don't have FB or other means to control power only to DDR(We
have 1.5V plane).I thought of measuring the power through decaps,but that
doesn't seems to cover the total power.

Any help is really appreciated.

Thanks,

Venu
