Jim: Please get you story straight at chipworks' blog. First, you mistyped the NOR MCP part number in the next to bottom paragraph - it is K5N1229ACD, not K5N122ACD. Second, you have labeled the bottom board GT-E2559 - is this the phone model number? Because Samsung E2559 does not exist. I also noted that the bottom board has at least two extra parts that are simply missing from the top board.
However, when I googled for K571229ACM I did indeed find various unlock logs. Specially, for the E2550 model I saw a September one from Pakistan, an October one from Turkey, a November one from Vietnam, and for the E2558 model, a November one from China.
So, the question is: are those phones containing K571229ACM counterfeit? Also, did you compare the performance between the PRAM and a NOR phone, before you decided to destroy it? For example, the time it took to take and erase 100 pictures, and how long the battery lasts?
In order to try and clarify this all, we took some time today to try and explain the challenges of finding PCM.

tipotech: Well, thank you for that information. Now, did the handset whose corpse we see in the pictures above come from Asia, North America, or Europe? In other words, who lied - Mr. Allan Yogasingam or "Jim.Morrison" or "BHD?" Because the real, commercial Samsung E2550 phone, like every other Samsung phone, contains Flash and no PRAM.
You are angry .. no one lied to you. you are todor / ecd fan
your are short ENER stock symbol for Energy conversion devices.. anything that comes out positive ref solar or pcm of which ENER Is involved in you are outraged . lies lies lies..
which for some reason you hate with an incredible passion .
More News coming .. so please take a chill pill or you might get sick
DestroCom: Samsung E2550 is a real, "underwhelming" phone that is indeed offered in Europe but it is NOT offered by any carrier in North America, for obvious reasons. It contains Flash NOR rather than PRAM. BHD's first post referenced GT-E550, a phone that does not exist - now "he" claims it was a "typo."
imageidol: Well, Mr. Allan Yogasingam, Technical Marketing Manager at UBM TechInsights, replied to me yesterday that "the story [they] contributed to EE Times mentions two phones from Samsung available for sale from Europe and Asia that contain this PRAM device." (so, two phones containing PRAM, one from Asia).
Commenter with alias "Jim.Morrison" claims that someone "actually had purchased two of these phones ... - [one] phone came from Europe and one came from N. America ... [the] phone from Europe had NOR and UTRAM and the North American phone which contained the PRAM and UTRAM." (so, just one phone with PRAM, and there is no Asian phone)
And commenter with alias BHD claimed "the phone" was Samsung GT-E550, but later apologized for the "typo." (so just one, non-existent phone)
So, at least one of these people lied. Did you get it now? The fact is, no carrier in North America offers Samsung E2550, for obvious reasons, and the commercial Samsung E2550 contains NOR Flash instead of PRAM. Therefore, TechInsights must have "analyzed" a fake, non-commercial phone. The PRAM chip, of course, is real and it sucks - and that is why no commercial product on the market uses it. Why is Samsung still silent about this "breakthrough" - a phone with PRAM in it?
How are you being lied to?
There's this little thing called 'Google' people are using these days. You should try it sometimes instead of being an angry internet troll.
I hope Chipworks or UBM Techinsights can tell us if PCM or NOR saves more area OUTSIDE the array, by requiring less error correcting logic. I estimate 512 million PCM cells each 125 nm X 125 nm gives 8 sq. mm. while the K571229ACM MCP is around 10x larger than this.
