Storage/Memory Hierarchy 40 Years Ago

1978 Memory/Storage HierarchyLast 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

Wafer Shortages and DRAM/NAND

Mark Thirsk, Linx ConsultingRecently 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

Putting DRAM Prices in Perspective

DRAM Low Spot Pricing 2011-2016For 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

DRAM Prices Down, But Not So Bad

DRAM Spot Price per GB HistoryFor the past ten months DRAM prices have been undergoing a steady slide.  Is the market in a crisis?  Not really!

Today’s low spot price of $4.30/GB puts us on a par with February 2013, a full two years ago (see chart).  DRAM makers have done a lot to reduce their production costs since that time, so their margins this quarter will be much better than they were in the first quarter of 2013.

But we are still a very long way from the bottom of the last market downturn.  In late 2012 spot prices reached a low of $2.52/GB, a full 41% lower than today’s lowest spot prices.

The Memory Guy models the production costs of leading memory chips, and DRAM manufacturing costs have been decreasing for the past several years at an average annual rate of about 30%.  That means that costs today are about half of what they were two years ago, and one third of their level this time in 2012.

So even though today’s Continue reading

Semiconductor Market Ends Year on a High Note

SIA LogoThe Semiconductor Industry Association this week announced the year-end World Semiconductor Trade Statistics (WSTS) revenues for 2014.  Worldwide sales grew 9.9% to reach a record total of $335.8 billion, outperforming the WSTS fall forecast.  Annual sales increased in all four regional markets for the first time since 2010. Memory was the fastest growing segment, increasing 18.2%, partly based on DRAM growth of 34.7%.It’s encouraging that all geographical areas experienced growth.  This implies that the world economy is finally on the mend.

The industry’s 9.9% worldwide growth was a good bit lower than Objective Analysis’ December 2013 prediction of growth in excess of 20%.  We admit that we overshot, expecting both higher bit growth and stronger pricing in DRAM and NAND flash than actually materialized.

The $335.8 billion number is really Continue reading

SIA: Memories Drive Record Semi Revenues

SIA LogoThe SIA yesterday released the WSTS semiconductor sales data for September.  Monthly revenues reached a record $27 billion driving third-quarter revenues to their own record of $81 billion.  This was the seventh straight month of semiconductor growth, the first such run-up since 2010.

This quote, by SIA CEO Brian Toohey really caught The Memory Guy’s eye: “Sales of memory products have increased sharply compared to last year and continue to be a major driver of industry growth.”

A lot has been happening to drive this increase in memory revenues: The recent SK hynix fire increased DRAM prices, but Continue reading

A Retrospect of Toshiba’s NAND Production Cut

Did Toshiba's 3Q12 Capacity Reduction Really Happen?There are some who still believe that Toshiba made good on its announcement to cut NAND flash production by 30%.  Let’s take a close look to see if that really happened.

Readers may recall that Toshiba stated last July that it would immediately cut NAND flash production by 30%.  At the time NAND was selling below cost for spot prices as low as 31 cents/GB.

The Memory Guy questioned both the wisdom of the move and its authenticity in a blog post at that time, since this level of cut would reduce Toshiba’s market share while increasing its Continue reading

DRAM Prices on the Rise

2013-03-12 DRAM Spot PricesThere’s been a lot of talk recently about increasing DRAM prices.  Although this trend has been ongoing since late November (see chart) it has only recently garnered the attention of the press.

What is going on, and how is it likely to play out?  The prices in the chart represent the lowest spot market prices reported by market tracker InSpectrum for the past year.  These prices typically remain below contract prices as long as there is an oversupply, and stay above contract prices during a shortage.

According to InSpectrum’s figures, today’s lowest spot market DRAM prices are about double Continue reading

Does the ‘Windows Bump’ Really Exist?

Windows Introductions vs DRAM Bit GrowthDRAM manufacturers often refer to “The Windows Bump” – a phenomenon that is believed to occur after every release of a new version of the Windows operating system.  According to this theory DRAM demand increases for a period following an introduction.

An example: in a recent article Kingston VP Scott Chen said that an increase in sales for Windows 8 might help raise DRAM demand, leading to more stable prices.

Demand is expected to pick up on the upcoming launch of Windows 8 tablets and Ultrabook PCs later in the second half of 2012.

Does the Windows Bump really exist?  The Memory Guy thought Continue reading

NAND Flash at 35 Cents per Gigabyte

35¢/GB NAND Flash - We are There Now!!!Last January at the Storage Visions Conference in Las Vegas (held every year just prior to CES) I asked the audience what they would do when NAND flash reached a price of 35¢ per gigabyte.  My projection (the dotted red line on the chart at left) was that prices would reach that level by the end of the year.

My audience was shocked to hear such a low price!

Price declines open up new markets.  It was time to think creatively, I said, because that’s where pricing would be by the end of 2012.

Well, I was wrong – according to Continue reading
