dan, surely you don't really think intel, dell, ibm, cpq, samsung, sony and toshiba picked rambus because it is inferior tech to ddr. surely in your heart, if not your pocketbook, you now realize that rambus is the hi-tech tech, and that is why the big boys are steering us that way. i went to school today. terrific teacher. studied sdram and ddrdram. learned tons...still reviewing notes. this is one of my favorite things that i learned. as a techie you may understand it even better than me. the topic at the time was aftermarket sale of dram and upgrading memory quantity. even i have done that before. this is a market for rmbs that i had not even considered. i quote... "the via initiative looks like it is set up for a fiasco...you might buy a pc133 machine with one dimm, then find it becomes unreliable when you add more." the situation for sdram becomes grim as granularity increases. one 256Mbit part of rdram has 32 Mbytes in it. 512 has 64 Mbytes. this is key...to upgrade you can add just one rambus part. with an 8-bit wide sdram part, you need to put 8 devices in parallel, with a 16-bit wide sdram part, you need to put 4 devices in parallel. t5his would cause the smallest addition to memory to be 512 Mbytes in one case and 256 Mbytes in the other...that is a heckuva lotta memory to buy and add if you don't need it. for wiley...or whoever asked about granularity. granularity is: the smallest size of memory that you can add to the system. this is getting bigger as parts get denser. the rambus advantage is that it can add as little as 1 part at a time. sdram uses parallel devices to get performance so must add 4-at-a-time or 8-at-a-time. rmbs is cheaper is guaranteed for smaller amounts of memory. in the aftermarket...the local store has memory specials...you buy for your rdram based machine 128Mbyte for $1x. and the cheapest sdram DIMM is $2x. the aftermarket is why techies won't touch a pc133 machine, even if intel fixes the mess...setting up for "trailing edge" technology, means that you will soon be paying the premium for end-of-life parts. unclewest hope i don't get too technical for ya! it is all dollars and sense to me!
