Maybe. HP's technology is based on titanium dioxide doped with oxygen vacancies between a crossbar switch. One problem is that oxygen vacancies move 10^13 times slower than electrons and holes in silicon. HP reports a switching speed of about 1 second. http://en.wikipedia.org/wiki/Memristor#Titanium_dioxide_memristor This is probably not a serious problem for neural networks because the connections could be written in parallel. It's actually much faster than the write times in the human brain, probably 10^4 seconds in the hippocampus and 10^8 seconds in the cortex. -- Matt Mahoney, [EMAIL PROTECTED] ------------------------------------------- agi Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: https://www.listbox.com/member/?member_id=8660244&id_secret=120640061-aded06 Powered by Listbox: http://www.listbox.com
