Bionz Processor does NR before RAW

I am curious. How does one know that NR is applied on-chip to raw images? Is not a raw file simply a 2D array of luminance values? If so, and this is what comes out of the chip, seems by definition to be uncooked raw.

Take a look at some of Sony's descriptions of their "BIONZ" image processor:

... circuitry that improves camera response time, screens out noise before RAW data conversion , handles Dynamic Range Optimization processing...

And from http://www.sony-asia.com/article/367326/section/product/product/dslr-a900 :

... the dual BIONZ engines apply advanced noise reduction algorithms twice — once prior to RAW data conversion and again during image processing — to ensure an absolute minimum of noise in final image data.
