So, how much is PRAM a danger to overtaking NAND technology, and ruining companies like Sandisk?

Samsung has now confessed its error and confirmed that the phase-change memory is a conventional chalcogenide alloy made of antimony, germanium and tellurium

I suspect that this is indeed an error, possibly induced by someone's lack of familiarity with the periodic table. I am getting third-party reports that Samsung's phase-change material continues to be a conventional tellurium alloy. However, I have sent an email to Samsung seeking clarification.

This is an announcement for the "first multichip package" with this memory in it. They announced the same device in it's own package in september of '09. http://www.eetimessupplynetwork.com/220100470?cid=RSSfeed_eetsn_eetsnRSS Samsung's patents get the chalcogenide components correct, so it's probably a marketing executive's gaff. There are electrode materials containing Titanium, however.

Mark: You were duped. This press release by Samsung is one big lie - it contains false and misleading statements. Here is the proof: www.newswire.co.kr/newsRead.php?no=470665 "PRAM, which stores data via the phase change characteristics of its base material, an alloy of germanium, antimony and titanium, provides three-times faster data storage performance per word than NOR chips" Unfortunately, the base material in Samsung's chip does NOT contain any TITANIUM! PRAM is made of tellurium, something quite different from titanium. The "3x faster" claim is also false. That is why Samsung does not even have the PRAM category on its memory product web site and there is no PRAM datasheet. Remember that old Samsung press release that claimed "30x faster?" www.samsung.com/global/business/semiconductor/newsView.do?news_id=322 By the way, do you also rememeber that Samsung claimed to have started mass production of the PCM chip K571228ACM in September last year: www.samsung.com/global/business/semiconductor/newsView.do?news_id=1042 What happened to that chip? (the chip in today's press release is K571229ACM) There is no race for PCM. The only race is who will get away with a bigger lie (after Samsung and Numonyx both failed to achieve profitability in the NOR market). Samsung seems to be in the lead again!
