Memory Markets – The Memory Guy

Intel’s Optane DIMM Price Model

With Intel’s Cascade Lake rollout last month came with a co-introduction of 3D XPoint Memory in a DIMM form factor, the Optane DIMM that had been promised since the first introduction of 3D XPoint Memory in mid-2015. A lot of benchmarks were provided to make the case for using Optane DIMMs (formally known as the Intel Optane DC Persistent Memory), but not much was said about the pricing, except for assertions that significant savings were possible when Optane was used to replace some of the DRAM in a large computing system.

So… How much does it cost? Well certain technical reports in resources like Anandtech probed sales channels to see what they could find, but The Memory Guy learned that the presentations Intel made to the press in advance of the Cascade Lake rollout contained not only prices for the three Optane DIMM densities (128, 256, & 512GB), but also provided the prices of the DRAM DIMMs that they were being compared against. I’ll get to that in a moment, but first let’s wade through the fundamentals of Intel’s Optane pricing strategy to understand why Intel has needs to price it the way that it has.

In Objective Analysis’ report on 3D XPoint Memory, and in several presentations I have Continue reading “Intel’s Optane DIMM Price Model”

Forecast Videos Prove A History of Accuracy

Every year the folks at VLSI Research provide The Memory Guy with an opportunity to share the latest Objective Analysis forecast with the world. They record a 20-minute video highlighting the forecast in a conversation between me and VLSI’s chairman, Dan Hutcheson.

There are now twelve videos on the site, one for each year from 2008 to 2019. That’s quite a collection!

Over the course of each video I not only present the forecast, but also give an overview of the thinking behind it. Typically I explain the impact of high or low capital spending in prior years, but in some forecasts I explain how other issues (in particular NAND flash’s excruciating conversion from planar to 3D) can create a shortage independent of capital spending patterns.

We also go over what went right or wrong with the prior year’s forecast. Things that go wrong are generally macroeconomic issues like the Continue reading “Forecast Videos Prove A History of Accuracy”

Where is Micron’s QuantX?

For more than a year The Memory Guy has been fielding questions about Micron’s QuantX products.

First announced at the 2016 Flash Memory Summit, this brand name has been assigned to Micron SSDs and DIMMs that use the Intel/Micron 3D XPoint Memory. Originally QuantX products were scheduled to ship in 2017, but Micron is currently projecting availability in 2019. My clients wonder why there have been these delays, and why Micron is not more actively marketing this product.

The simple answer is that it doesn’t make financial sense for Micron to ship these products at this time.

Within two weeks of the first announcement of 3D XPoint Memory, at the 2015 Flash Memory Summit, I knew and explained that the technology would take two years or more to reach manufacturing cost parity with DRAM, even though Intel and Micron loudly proclaimed that it was ten times denser than DRAM. This density advantage should eventually allow XPoint manufacturing costs to drop below DRAM costs, but any new technology, and even old technologies that are in low-volume production, suffer a decided scale disadvantage against DRAM, which sells close Continue reading “Where is Micron’s QuantX?”

Intel’s Losses Amid Others’ Gains

Why has Intel’s NVM Solutions Group (NSG), the owner of the company’s NAND flash, SSD, and 3D XPoint businesses, been losing money during a time when all other manufacturers are more profitable than they have been in years?

This is a question that certain investors have put to The Memory Guy for the past year or so, and it deserves some explanation.

This post’s graphic compares Intel’s NSG net profit margins to the margins published by other memory companies. (Click on it to see the whole chart.) This isn’t a completely clean comparison since the data for Samsung, SK hynix, and Micron includes DRAM, and recent quarters are missing for Western Digital (SanDisk) and Toshiba since these companies have stopped sharing comparable financials, but it still serves as a relatively clear indication that Intel’s NSG (blue) is losing money while all other companies are quite profitable.

Something seems dreadfully Continue reading “Intel’s Losses Amid Others’ Gains”

Emerging Memories Today: New Blog Series

There’s never been a more exciting time for emerging memory technologies. New memory types like PCM, MRAM, ReRAM, FRAM, and others have been waiting patiently, sometimes for decades, for an opportunity to make a sizeable markets of their own. Today it appears that their opportunity is very near.

Some of these memory types are already being manufactured in volume, and the established niches that these chips sell into can provide good revenue. But the market is poised to experience a very dramatic upturn as advanced logic processing nodes drive sophisticated processors and ASICs to adopt emerging persistent memory technologies. Meanwhile Intel has started to aggressively promote its new 3D XPoint memory for use as a persistent (nonvolatile) memory layer for advanced computing. It’s no wonder that SNIA, JEDEC, and other standards bodies, along with the Linux community and major software firms are working hard to implement the necessary standards and ecosystems to support widespread adoption of the persistent nature of these new technologies.

This post introduces a Continue reading “Emerging Memories Today: New Blog Series”

Memory Market Falling, as Predicted

It’s earnings call season, and we have heard of a slowing DRAM market and NAND flash price declines from Micron, SK hynix, Intel, and now Samsung. DRAM prices have stopped increasing, and that can be viewed as a precursor to a price decline.

Samsung’s 31 October, 2018 3Q18 earnings call vindicated Objective Analysis‘ forecast for a 2H18 downturn in memories that will take the rest of the semiconductor market with it.

Those familiar with our forecast know that for a few years we have been predicting a downturn in the second half of this year as NAND flash prices fall, followed by a DRAM price collapse. After the DRAM collapse the rest of the semiconductor market will undergo a downturn.

We’ve been calling for this downturn for some time. Dan Hutcheson at VLSI Research has been videotaping our forecast every December for the past Continue reading “Memory Market Falling, as Predicted”

How to Worsen a DRAM Shortage

In an interesting twist to today’s ongoing DRAM shortage, the Fuzhou Intermediate People’s Court, Fujian Province, China today granted a preliminary injunction to prevent Micron’s Chinese subsidiaries from manufacturing, selling, or importing certain DRAM modules and solid state drives in China.

This injunction, according to a Micron press release, was filed without allowing Micron to present its defense, a process which Micron finds to be: “inconsistent with providing a fair hearing through appropriate legal processes and procedures.”

Micron’s customers in China will find that the DRAM shortage has just become even worse than it already was. Before today China’s government was concerned enough about the shortage’s rising DRAM prices to have launched a price fixing investigation only one month ago. One result of today’s decision will be that there will be less DRAM in China, and that will probably cause prices to rise even more.

What will be the impact to Micron? I find it unlikely that this injunction is likely to change any DRAM maker’s business much during a shortage. Any lack of Micron DRAM in China is likely to be serviced by Samsung and SK hynix, but since there’s a shortage, these companies will need to reduce their shipments outside of China to satisfy Continue reading “How to Worsen a DRAM Shortage”

Storage/Memory Hierarchy 40 Years Ago

Last year I stumbled upon something on the Internet that I thought would be fun to share. It’s the picture on the left from a 1978 book by Laurence Allman: Memory Design Microcomputers to Mainframes. The picture’s not too clear, but it is a predecessor to a graphic of the memory/storage hierarchy that The Memory Guy often uses to explain how various elements (HDD, SSD, DRAM) fit together.

On the horizontal axis is Access Time, which the storage community calls latency. The vertical axis shows cost per bit. The chart uses a log-log format: both the X and Y axes are in orders of magnitude. This allows a straight line to be drawn through the points that represent the various technologies, and prevent most of the technologies from being squeezed into the bottom left corner of the chart.

What I find fascinating about this graphic is not only the technologies that it includes but also the way that it’s presented. First, let’s talk about the technologies.

At the very top we have RAM: “TTL, ECL, and fast MOS static types.” TTL and ECL, technologies that are seldom Continue reading “Storage/Memory Hierarchy 40 Years Ago”

Wafer Shortages and DRAM/NAND

Recently I have been hearing concerns that an impending wafer shortage might drive today’s DRAM and NAND flash shortages to epic proportions.

The Memory Guy doesn’t pretend to have any understanding of the raw wafer business, so I decided to consult Mark Thirsk, managing partner of Linx Consulting. Mark has been in this industry for quite a while and has a very good understanding of the ongoing status of the semiconductor materials supply chain.

Mark and I were on a panel together at SEMICON Korea in February, and he presented an interesting chart to compare the costs of different technologies. I asked him about this chart as well.

Here’s what Mark had to say:

“Our information is that major Continue reading “Wafer Shortages and DRAM/NAND”

Micron and Intel to End NAND Flash JV

It came as a surprise to the Memory Guy on Monday to receive a press release from Micron indicating that Intel and Micron had decided to end their NAND flash partnership.

This agreement, which was begun in 2006, helped the two companies to aggressively ramp into the NAND flash market by combining their resources. NAND flash makers (as well as DRAM makers) need to make very substantial capital investments to participate in the market, and that’s not easy for a new entrant. Micron at that time was a very small NAND flash maker, and Intel wasn’t involved in the NAND flash market at all, so neither was in a position to succeed. By combining their resources the companies were able to become important contributors to the market.

The agreement initially appeared to be modeled after the very successful joint venture that Toshiba and SanDisk enjoyed. Each company would contribute half of the JV’s capital investment, and the same designs would be used to make both companies’ chips.

Over time Intel found itself in a familiar Continue reading “Micron and Intel to End NAND Flash JV”
