OK. I was thinking more along the lines of PROM (i.e. random access) but I can imagine there's nothing now more useful than flash.

- pjc50 11y agoThere is "antifuse", although it's a little slow to program. Commonly available on chips in small amounts for secure key storage, serial numbers, calibration etc. I'm not aware of anyone selling standalone parts, but here is an IEEE paper: http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=1240972&url=http%3A%2F%2Fieeexplore.ieee.org%2Fiel5%2F4%2F27824%2F01240972.pdf%3Farnumber%3D1240972 http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=124097... (512Mb in 2003!) If Google really wanted to, they could make a couple of petabytes of slow-to-write memory by commissioning it themselves for low numbers of millions of dollars. But I suspect they value the rewritability. See also http://www.eetimes.com/document.asp?doc_id=1328234 http://www.eetimes.com/document.asp?doc_id=1328234
