Move over flash: Here comes phase change memory

University of California San Diego researchers next week plan to demonstrate a solid state storage device that uses the memory of change of phase to blow away from traditional hard drives and even new flash readers.The Moneta system, which is presented at the Design Automation Conference (DAC 2011) in San Diego, is thousands of times faster than a hard disk of the agreement and up to seven times faster than disk memory flash according to the student-faculty research team.The memory of change of phase used in the device stores the data in the structure of glass and a metal alloy called CHALCOGENIDE that changes States as atoms are rearranged. As the flash memory used in all areas of the laptops to the iPads, PCM involves no moving parts, in accordance with the University.Moneta uses first-generation PCM chips Micron Technology and can read large pieces of data up to 1.1 GB per second in an efficient average power."As a society, we can collect all these very, very quickly - data much faster that we can analyze with disk storage systems, classic," said Steven Swanson, Professor of computer science and engineering and Director of the Non Volatile systems Lab (NVSL), in a statement.  "Change of solid phase based on the memory of the storage devices will iterate through all of these data, make sense and extract useful information much faster." It has the potential to be revolutionary. »Swanson said he wants to build a device Moneta of second generation within six to nine months and provides commercial products in the coming years. Work must be done on the software front to face the new equipment, he said.PCM has been under investigation for years by the chip and the storage of companies such as IBM, Intel, Infineon and Micron. Samsung last year announced that it was PCM for smartphones in a package of smart.
