RE:"Currently RDRAM is 2 times? 3 times? 4 times? more expensive than DDRAM." About 10 times more than SDRAM at Muskin...Retail... Right now, RDRAM is the laughing stock of RAM. Jim

Re: DRAM post - MEA CULPA!: Ted, I made a pretty bad typo on that post in this section: DDR DRAM is 64 bits (8 bytes) wide and runs at 200, 266, 333, 366, and 400 MHZ data rate (1/2 that speed, double data rate) x 8 or 1,600, 2,128, 2,664, 2,928, and 3,200 MB/sec. DDR DRAM should be RDRAM is 16 bits (2 bytes) wide and runs at 566, 712, and 800 MHZ data rate (1/2 that speed, double data rate) x2 or 1,132, 1,424, and 1,600 MB/sec. 2 1,600 MB/sec rambus channels can be combined to equal one 3,200 MB/sec DDR channel. Sorry about that, I was on the phone while typing and can't seem to handle doing two things at once - thank goodness I wasn't trying to walk and chew gum, eh? Hopefully, with that correction, the post will make more sense! Also: DRAM in various versions long ago replaced SRAM as main memory because it is an order of magnitude cheaper and uses far less power. (though now that DRDRAM has entered the scene, that's not quite as true as it once was!) Rambus is running about 6 to 10 times the price of other DRAM - expect that to go lower, but not much lower than double the price due to the technical factors listed in the post - the rambus royalty fees are just extra gunshots into the corpse. Edelstone seems to have had a lot to do with getting the rambus IPO for Dean Witter and appears to be an honest politician - he stays bought. Again, apologies for the error - Bill Jackson even sent me a message to compare lines 2 and 3 but I only looked at the second and third lines of the message. Regards, Dan
