Floating Gate NAND densities eetimes.com me: Why is it that no one ever talks about MirrorBit(charge trapping)? It's almost as if SPSN were the ugly step sister that no one wants to talk about. Anyway, Son of ORNAND(II) is supposed to be twice as dense as ORNAND. However, I'm not sure if SPSN management is comparing the 90nm version or the 65nm version. SPSN already has quadbit and it's supposedly getting better all the time. Right now at 90nm the highest density SPSN chips I've seen were 3Gb. At 65nm that should go up a bit and at 45nm even more, and thats ORNAND, not qbit. The interesting thing in the article is the way DRAM seems to be having trouble scaling. If SPSN can really make a type of NOR/DRAM at a lower cost/higher density how high is the sky? I get tired of reading about NAND as if it were the only NV memory out there. Yeah, data storage is important but without brains its value is limited. Having both fungible XIP NOR and ORNAND in one package seems to have a whole lot of possibilities. Especially if a very dense version of qbit is added to the chip, like a 2nd level cache. Now if the NOR can be made to run as fast as DRAM and uses significantly less resources you've got a killer product. Call me crazy, but I wouldn't be surprised to see an entry from SPSN in the SSD market at some time. Using NOR/DDR as the controller and a combination of ORNAND 2 and Qbit seems like it should work, and use less power? From what I've been reading the controller is going to be the hard part of the SSD particularly since processing is going to be a lot more random than sequential. NAND is great at sequential but not so hot at random.
