After a big 3D XPoint launch one year ago almost anyone would expect for Intel to have had a lot of exciting new news to share about the technology at last week’s Intel Developer Forum (IDF). Those who were watching for that, though, were in for a disappointment.
For readers who don’t remember, Intel and its partner, chipmaker Micron Technology, announced a new memory layer in July 2015 that would enable in-memory databases to expand well beyond the constraints posed by standard DRAM memory. The pair also boasted the additional benefit of being nonvolatile or persistent – data would not be lost if the power failed. This technology promised to open new horizons in the world of computing.
Intel devoted a lot of effort to promotion and education during the following month’s IDF, and even demonstrated a prototype 3D XPoint SSD that performed seven to eight times as fast as Intel’s highest-performance existing NAND flash SSD – the DC S3700. Although a DIMM form factor was disclosed, no prototypes were on hand. Both were given the brand name “Optane”.
At a technical conference hosted by the IEEE this week IBM announced the results of nearly a decade of research in which its scientists have been investigating the emerging technology known as “Phase Change Memory” (PCM). The scientists presented a means of successfully storing three bits per cell for the first time, while also addressing all of PCM’s challenging idiosyncrasies, including resistance drift and temperature drift.
Commonly referred to by the erroneous nickname “TLC” for Triple Level Cell, this technology squeezes three bits of data into the space of a single bit, essentially cutting the cost per gigabyte to about one third of that of a standard memory chip making it closer in cost to flash.
With this step IBM expects to help drive a new memory layer into existence, one that will fit between the cheap and slow NAND flash used in SSDs and the fast but expensive DRAM used for main memory. Such a layer would improve the cost/performance of all types of Continue reading
Objective Analysis has just introduced a new report that you might want to consider: A Close Look At The Micron/Intel 3D XPoint Memory.
The report covers the Intel-Micron 3D XPoint memory and includes Intel’s new Optane support products that are based on this technology. The report explains the technology and its special manufacturing challenges. It includes details of how 3D XPoint memory will be used, and provides an analysis of the benefits of its persistent nature.
Forecasts project how the market will develop and include optimistic and pessimistic forecast scenarios. Particular attention has been paid to its impact upon the DRAM, SSD, and other markets. Finally, the report analyzes different end-market segments to predict how this technology will impact each of them.
The Memory Guy, report author Jim Handy, will present the report’s findings during the Pre-Conference Primer of the Storage Network Industry Association (SNIA) Storage Developer Conference (SDC) this Sunday, September 20, at 2:00 PM, In Santa Clara, CA.
This breakthrough report is based on Continue reading
