This is right on. As a designer of system on a chip I agree.
In a system on a chip design the DRAM data path width can
be 64 bits, no muxing of addr/data needed since I/O count
is not an issue. Therefore, RMBS can't take advantage of
system on a chip designs.

But RMBS concept can be used with advanced CPUs where the DRAM is
a seperate chip. The concept is good, but will DRAM mfgr's
get together and write a spec for a protocol which is
nearly as good but would save the license fees? This can't
happen if Intel designs in RMBS interface. DRAM mfgrs will
have to license RMBS as a minimum to "claim they are RMBS
compatible". How much of RMBS does intel own? Maybe this
is just another way for intel to get more $$ on each PC
sold.

Lots of rambling.... IMO it's difficult to put a value on
this company.
