<Each Sony PlayStation 2 will require two 128-Mbit Direct RDRAM chips.> That makes a lot of sense. Thanks, Dave, for that little quote. In that sentence, I suppose "chip" is different from RIMM, or more generically, "module." A normal DRDRAM RIMM will have eight "chips" on it sitting on a single channel. A RIMM based on 128-Mbit technology will actually have eight of those 128-Mbit DRDRAM chips, for a grand total of 128 megabytes. To save on costs, however, Sony will only need two of those DRDRAM chips, probably soldered directly onto the console motherboard itself rather than plugged in via a RIMM. Also, because bandwidth is more important than capacity, each chip will have its own dedicated DRDRAM channel. This is different from multiple chips sitting on one channel. I expect Timna-based PC's (and perhaps Timna-based set-top boxes as well?) to support DRDRAM chips soldered directly onto the motherboard as well. If those PC's don't need more than 64 MB of memory, soldering four 128-Mbit DRDRAM chips onto the motherboard would be a great price/performance combination. Tenchusatsu
