resistion: Let's not forget that in 2006 Samsung already knew what the Perfect RAM was:
"More scalable than any other memory architecture being researched, [it] features the fast processing speed of RAM for its operating functions combined with the non-volatile features of flash memory for storage, giving it the nickname : perfect RAM."
Samsung, as it turned out in this case, were either quite clueless, or maliciously deceptive.
no.name_#4: If you actually read the comments section of the article you referenced, you would have realized that the ONLY known handset unit with PRAM in the world is now dead - we don't even know whether it functioned. How can PRAM be adopted "in mobile phone applications," if the only device that "adopted it" has been completely and utterly destroyed? Yes, there are rumors of a few more fake, counterfeit E2550/E2558 handsets with PRAM floating around in Asia, but no one seems to have caught them yet. Therefore, the Samsung statement is false, unless Mr. Kim can show us some "mobile phone applications" that are NOT dead right now.
The temperature sensitivity of PRAM is not the biggest problem in a cell phone (although it is a major concern). The biggest problem is power consumption in write and the write speed. See how careful Mr. Kim qualified the usage "as a code storage memory?" Unfortunately for him, NOR works better than PRAM as a code storage memory, and it is way cheaper, and proven, as evidenced by the fact that the COMMERCIAL, genuine Samsung E2550/E2558 phones actually use NOR memory for code storage.
In the live presentation, he tipped ReRAM as the "universal memory". A little strong, but more surprising after their recent fling with PRAM. Another surprise is their 27 nm NAND is floating gate - what happened to TANOS? Also, they are finally acknowledging the EUV litho as becoming a tad expensive, so are looking at nanoimprint and directed self-assembly.
Didn't EETime publish in 12/2/2010 http://www.eetimes.com/electronics-news/4211190/Phase-change-memory-found-in-handset UBM TechInsights has announced it has found a phase-change memory die inside a multi-chip package inside a mobile handset?
It seems "PRAM is now being adopted in mobile phone applications as a code storage memory." is indeed a true statement.
As a consumer, if I had a PRAM cell phone, my concern would be PRAM's temperature sensitivity, its most notable drawback, .... having a smaller operating window compared to some flash.
I wouldn't want my cell phone memory erased if I should leave behind my phone in a car parked in the hot Phoenix summer sun!!
"PRAM is now being adopted in mobile phone applications as a code storage memory." Really? What did Mr. Kim mean exactly? Other than one counterfeit, non-commercial Samsung E2550 with PRAM (now dead and dismantled), there is no evidence that his statement is true (although there are rumors that a few more PRAM-based counterfeit E2550 and even one counterfeit E2558 exist in the wild). The actual commercial Samsung E2550 and E2558 phones use NOR. It appears the technologist from Samsung Electronics Co. Ltd. is attempting to mislead the public.
