Recently, the joint venture of Intel and Micron - IM Flash Technologies - has conducted an annual conference. The key point of the report co-director of IM Flash Technologies - Bleloka Guy - has become the story of memory 3D XPoint. As you know, the first mass production of chips 3D XPoint should master joint venture plant in Utah. Until now, Intel and Micron kept secret principle of 3D XPoint memory. As justified by the developers, the technology has not been fully worked out . The transition to production inevitably would lead to the disclosure of secrets, because require very specific equipment and raw materials. So then it was absurd to hide the details. Therefore chef IM Flash Technologies said that 3D XPoint memory based on technology shifts the phase state of matter. It is well known to us in the memory of PCM or PRAM.
The effect is reversible phase change of matter state discovered by Ovshinsky Stanford 55 years ago. The brightest of its practical application - is the production of recordable CD, DVD and Blu-ray discs. The laser beam needs to heat parts of the disk in the crystalline state, the amorphous. The current through the memory cell heats the material in its composition and changes its phase state, and therefore, the resistance to the current. Nevertheless, the memory of PCM had one flaw that slowed its spread - it is a large area of the cell, or low-density recording. It seems that Intel and Micron proposed Cross-layered architecture solved the problem with the recording density.
So, Intel is under the guise of revolutionary development presented us memory PCM. At the same time, a special layout 3D XPoint requires considerable upgrading of equipment. For example, if a simple change of scale NAND-flash usually increases capital costs by 20-30%, the introduction of the production 3D XPoint that awful, generational change issue 3D XPoint entail an increase in capital costs by 3-5 times.
Intel and Micron are determined to proceed with the large scale production of memory 3D XPoint and drives based on it. To do this, Intel will begin to modernize their production in the Chinese city of Dalian, and the company will prepare Micron factory in Singapore, in addition to the factory in the US state of Utah.
