PlayStation 3 is the main user memory type XDR, and after Nvidia not be using XRD and prefer GDDR5, Sony PlayStation 3 is the only mass-produced products which uses XDR RAM. Elpida as a company XDR manufactures, has ceased production of XDR.
So this begs the question: Is Sony abandoning XDR for their next die shrink of Cell and moving to GDDR5?
IBM already made a version of Cell that used DDR2 so it´s not like Cell is designed around XDR. The only technical hindrance as I see it, is if it could break BC with current games for some reason?
As I see it they could also easily replace the GDDR3 memory (4 pcs 512 Mbit units) of the RSX with GDDR5 (2 pcs 1 Gbit units) and cutting the bus from 128 bits to 64 bits as well in the process.
Leaving the XDR niche memory and going with standard GDDR5 memory units would probably lower the price of the memory in PS3. XDR never took off in the mass market beside the PS3, letting it go at this stage would make sense in my opinion.
