Barry, I looked at the nine patents you mentioned. None cover CPU or memory controllers. One of the patents 6,034,919 is not a RMBS patent, it is assigned to Compaq and relates to "memory systems" (as a memory board). Some of the patents, however cover both devices and methods of operating such devices, thus controllers that send commands or requests to the DRAM and use the method would be covered, the rate of course depends on how many of the controller functions are covered by RMBS and which control functions are not. What I found interesting, however is that in the abstract of 6,038,195, they discuss 2 semi devices at least one of which is a memory, but the claims are mute on what the second (controller? CPU other devices interfacing with the memory?) device could be and the combination of the two devices (in essence the subject of the patent according to the abstract) was not allowed. Typically it could very well be that they attempted obtaining protection for the combination of a DRAM and its controller, but the PTO turned them down, That you can find out only by looking at the "file wraper". Having said all this, they have methods claims all over the place, both as independent patents (6,032,214 and 6,034,918) and within the normal device patents. It could very well be that your group of patents relates only to the controversy with the DRAMURAI and thus other patents (out of the group of 102 patents issued) do cover additional interfacing devices, and I am almost sure communication means and methods (covering the bus themselves as well as the nature of th signals that propagate on those buses). All the patents you cited address memory devices per se (except 6,038,195 but the claims are only on the memory devices and methods of operating them) I apologize for not being "more definitive" on that.
