Can we interafce x8 DDR3 memories with DMC interface of ADSP-SC587?

Hello,

I have seen one statement saying "4-bit and 8-bit wide DDR2 DRAM memories are not supported" in DDR3 section. 

This statement is confusing, as it is written in DDR exclusion feature section and talking regarding DDR2. Please clear this statement. 

Also if this statement is true for DDR3 as well, then let us know, "can we use 2 x 512Mx8 DDR3 memories with each DMC (x16) interface of ADSP-SC587"?

Thanks and Regards
