For almost two years there has been a lot of worry about DRAM spot prices. This post’s graphic plots the lowest weekly spot price per gigabyte for the cheapest DRAM, regardless of density, on a semi-logarithmic scale. (Remember that on a semi-logarithmic scale constant growth appears as a straight line.)
The downward-sloping red line on right side of the chart shows that DRAM prices have been sliding at a 45% annual rate since October 2014. This has a lot of people worried for the health of the industry.
What most fail to remember, though, is that DRAM spot prices hit their lowest point twice in 2011, at $2.40 in August, and then $2.20 in November. Today’s lowest DRAM spot prices have only recently dipped below the $2.52 point hit in October of 2014.
The black dotted line in the chart is intended to focus readers’ attention on DRAM costs, which decrease at a 30% average Continue reading
Micron has announced that it is sampling a new 128Gb NAND flash chip based upon a 16nm process, with production slated for the fourth quarter. To The Memory Guy’s knowledge this is the tightest process available.
The company, with its partner Intel, gained a lead with its 20nm process generation through its use of a Hi-k tunnel dielectric, a new material that replaces more conventional silicon dioxide layer with a new material (Micron won’t say what) that yields the same capacitance with a thinner layer. This has become very important with today’s tight processes because of issues of inter-cell interference.
Other NAND makers are migrating to Continue reading
Over lunch today I had a conversation with an alum of McKinsey Consulting who remarked that the DRAM business behaved in a way that was similar to the McKinsey Steel Model. For those unfamiliar with this model I found a slideshow HERE that refers to it a good deal. (So far I have not found a tutorial on the model itself, but if anyone knows were to find it The Memory Guy would highly appreciate hearing about it.)
One interesting thing is that this particular McKinsey alum was not the first to point this out to me. About 15 years ago a family friend/McKinsey alum told me exactly the same thing. It seems that the economics of the DRAM business have changed little over the past 15 years, and the McKinsey steel model applies to DRAMs just as well now as it did then.
In a nutshell, the model posits that the market price for Continue reading
