Scumbria, <Integrated DRAM controllers are a bad idea because it gates the ultimate cost- time to market.> Why? I would come to the exactly opposite conclusion. i.e., integrated DRAM controller IMPROVES time to market. No need to keep getting stuck with the same old motherboard signal integrity problems. <DRAM changes all the time, ..> As I said there was just one fundamental change in DRAMs in the last decade so may be you can explain where you are coming from. <...and having an integrated DRAM controller forces CPUs into obsolesence quickly. > What is the basis for the "obsolesence"? In the last 3 years AMD had K6, K6-2, K6-3, K7, K7.5, Thunderbird, Duron and is about to get to Palomino. It looks to me processors get obseleted faster than memory types. How do you see this differently? <The time to design and qualify a new spin is extremely expensive, and makes integrated memory controllers a real, real bad idea in the desktop market.> See above.

tegrated DRAM controllers are a bad idea because it gates the ultimate cost- time to market. DRAM changes all the time, and having an integrated DRAM controller forces CPUs into obsolesence quickly. Is there any reasonable (in terms of cost and development time) way to get a integrated RAM controler that is flexible enough to work with different types of memory? It would still have the problem of not working with brand new types of memory that were not anticipated at the time of the memory controlers design, but at least it would avoid the problem that Timna had. If Timna's memory controler could have worked with RDRAM and SDRAM then maybe it would not have had to be canceled. Tim
