Regarding RMBS:

Problem (1) The technology is relatively easily circumvented,
preventing significant excess licensing. In other words a good
engineer can make a DRAM or DRAM controller that will meet
the RMBS interface specification without violating RMBS
patents, in my opinion. The reason for this is that the I/O logic
on a DRAM is such a tiny percentage of the die area that
using an inefficient design really doesn't drive the chip cost
up any.
Problem (2) When we actually get to system on a chip, the
RMBS spec is no longer needed at all. The whole purpose
of the RMBS spec is to reduce the number of pins required
to interface to a DRAM, while increasing speed through
those pins. On a chip, neither of these is an issue.

In other words, RMBS could be a "fad" technology for DRAM.
One that soon gets replaced with a newer design. So valuing
it is kind of rough.
