"The delays have largely stemmed from two sources. First, it's not an easy technology to master. In phase change memory chips, a microscopic bit on a substrate gets heated up 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. The two different crystalline structures exhibit different levels of resistance to electrical current, and those levels of resistance in turn are then as ones or zeros by a computer. Data is born."

It does not matter to e.Digital if it's PRAM (crystalline principles) / NOR/NAND ( floating gate utilizing metal oxide principles).....or MRAM(utilizing Magnetic principles). It does not matter what the cell structure make up is or what atom size(density) they are.

e.Digital's patented logic principles will drive any of them.
