End of Moore in sight for memory?

The HPC Watercooler links to an article about speculations that memory will hit the end of Moores Law sonner than processors.. But is this really a problem. I don´t think that we need even more memory on a single chip any time soon. What we need is a reduced thermal budget per 1 Gigabyte of memory. The biggest problem in designing “really big servers” is to get the cooling right for these large amount of memory.
