While we were initially told at the XPoint announcement event Q&A that the technology was not phase change based, there is overwhelming evidence to the contrary, and it is likely that Intel did not want to let the cat out of the bag too early. They act as insulators at room temperature and as conductors when heated (or when doped). The mate-rial exhibits a change in material properties, both electrical and optical, when changed from the amorphous (disordered) to the polycr ystalline (regularly ordered) state.

An interesting thing to note about the above is that there is no ‘erase’ required before programming a cell as is the case with NAND flash. << I should point out that we don’t need nearly that high of a voltage to perform a read, as even 0.1V would produce a readable difference in current between the two states used in our example. Yeah, I read a lot about him while researching this piece. /Type/ExtGState It took NAND flash decades to make it into usable SSDs, and another decade before climbing to the performance levels we enjoy today. �� C Phase change memory produces very fast read and write speeds at lower power than conventional NOR and NAND flash memory, and allows for bit alterability normally seen in RAM. While we do not have absolute confirmation of the precise material compositions, there is a significant amount of evidence pointing to one particular set of technologies. July 17, 2012. Now that the ovonic switch is a mass production reality, how long before its used as a true brickable chip. Phase-change memory, to recap, is a chalcogenide (glass-like) material which changes its internal state from amorphous to crystalline and back again when the appropriate amount of electricity is applied to it. To reset the cell, we apply a much higher voltage, pushing currents and temperatures high enough (~600C) to heat the material to a molten state. Intel and Micron had developed other non-volatile phase-change memory (PCM) technologies previously; Mark Durcan of Micron said 3D XPoint architecture differs from previous offerings of PCM, and uses chalcogenide materials for both selector and storage parts of memory cell that are faster and more stable than traditional PCM materials like GST. /ColorSpace/DeviceRGB stream The amorphous state resembles a glass, while the crystalline state more closely resembles a metal. The voltage is then removed and the material rapidly cools, passing through the crystallization temperature region too quickly to form any crystal structure, ‘freezing’ it in the amorphous state. Chalcogens blue boxed. endobj /Filter/FlateDecode Since the material is now acting resistive, it dissipates heat and therefore increases in temperature.
