"I think they also claim a patent on DDR"

I think this is only when used on a memory bus. The prior art on moving data on both clock edges goes waaayyy back, heck I did a design with 74C and 4000 series CMOS in the early 80's that used that method. It wasn't for performance reasons needless to say, but I was able to reduce the number of gates that way...

dale, Well, they can make a double speed clock and to hell with Rambus. Double and other ratio clocks have been around for a while

Dale,

On the other hand. AMD has said that AGP could hang off the LDT bus.

When did they say it? It would be great if AMD managed to find a way to avoid the direct AGP connection to Northbridge.

AMD, Alliance Semiconductor settle patent litigation

NEW YORK, Dec 14 (Reuters) - Computer chip makers Advanced
Micro Devices Inc. and Alliance Semiconductor Corp. have settled
their patent litigation, and Alliance will pay AMD an undisclosed
sum for past damages, the companies said on Thursday.

Under the settlement, the companies will drop their claims and
counterclaims against each other, they said.

AMD filed suit against Alliance in 1996, alleging that
Alliance's Flash memory devices infringed two AMD Flash memory
patents.

As part of the settlement, the companies have submitted to the
San Jose District Court a consent judgment that the two AMD
patents are valid and enforceable and that certain Alliance Flash
memory devices infringed AMD's patents.

The companies also said they will enter into a royalty-bearing
license agreement for future sales of two existing Flash memory
products.

How much money I wonder?

The way I see it, Synchronous SRAM was around long before Rambus came into the picture, so the key is to use a Synchronous SRAM cache as a buffer between the processor and the DRAM cells. Thus, for "CAS" access, the processor could use Synchronous SRAM protocols. The DRAM cells could be standard EDO DRAM cells, which are not covered by the Rambus patents, with all accesses other than refresh passing through the integrated SRAM "cache lines".

Dale, I think the DRAM with SRAM cache is more or less the idea behind EDDR. I think there's also something called EDRAM (Enhanced as opposed to embedded eDRAM) out there already, associated with Ramtron, as opposed to the money for nothing people. An article on some of this stuff that I posted a few weeks back: lostcircuits.com .

I'm sure the money for nothing people will claim to have invented this too, regardless of how it ends up being developed, but maybe the SRAM angle will defeat them, if they don't go down on other matters before then.

Cheers, Dan.

Dale: AMD would be fools to integrate the memory controller into Clawhammer before the Rambus lawsuits are settled

Due to design times, I say integrate the memory controller NOW, buy a Rambus license later if needed (which I don't consider likely). The performance increase would be well worth it.
