Numonyx has samples of traditional NOR flash at 32 nanometers. What does the author mean? Traditional = floating gate? Regards

Article: The delays have largely stemmed from two sources. First, it's not an easy technology to master. In phase change memory chips, a tiny laser heats up a microscopic bit on a substrate to between 150 degrees and 600 degrees Celsius. The substrate is made of the same stuff as CD disks. The heat melts the bit, which when cooled solidifies into one of two crystalline structures, depending on how fast the cooling takes place. me: I thought the PCM process INTC was developing was electrically activated not laser based? Article: There is also no erase cycle, making it similar to DRAM. me: I wonder how PCM will compare with SPSN's DRAM? How will they get around all the patent stuff that has built up around CDs and DVDs if they're using lasers? Conventional DVDs already write multiple tracks, but it's still serial in nature. So are we back to a spinning platter? The last thing I read they were talking about MEMs moveable heads. What is really going on? If their talking lasers then the density is limited by the EMR wave length of the laser and how many levels of data they can lay down.
