KISS, Rambus has been around since the mid 90's. DDR was designed within the last two years. Rambus uses a complicated ethernet-type interface to the CPU, and the stuff generates a BUTTLOAD of heat. I'm afraid you have no clue as to what you're talking about. Intel selected the DRDRAM design over SLDRAM and DDR DRAM in December 1996. Rambus has been working on chip-to-chip communications since 1990 (that's when they incorporated) and probably before that at Stanford. Direct Rambus DRAM hasn't been any more available than DDR -- they just began producing it late last year. The version of Rambus memory that was used in the Nintendo was a different (slower) design. As for the heat, that's simply a function of the higher speed at which the memory interface runs. It is a packetized interface for commands, but not for the data (a 2 byte wide data path). Or maybe you could consider it a packetized 16 byte wide data path. Whichever. But it's hotter because it runs faster. Just like processors. Where are you getting your (mis)information? Dave
