IBM is implementing DRAM on their CPU's (http://www.cbronline.com/article_news.asp?guid=F7024759-9373-47F1-A12A-B96D59BA4BD1 ). IBM is migrating from SRAM on DRAM on CPU. The main advantage is that DRAM has less problems with current leakage. DRAM also has a higher memory density.

RAM on cpu, 8-16 cores coming... LEARN ERLANG AND HASKELL! Neither a breakthrough nor new--just breathless PR. On the very oldest DRAM's the capacitor was a transistor. And HP had DRAM on PA-RISC before Carly was stupid enough to believe Intel/Itanium PR. When some company finally says either "We replaced our DRAM completely with FLASH" or "We replaced our DRAM completely with SRAM", then you should start getting excited. -a -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
