Does the ‘Windows Bump’ Really Exist?

DRAM 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.

Samsung Revenues Reflect NAND Price Increase

NAND prices have increased since July, and that appears to have helped Samsung to increase its memory revenues in the past quarter. That comes as a welcome change!

As this post’s graphic illustrates the company has has seen downward-trending memory revenues for five of the past six quarters, but Q2 revenues increased by ten percent. Interestingly enough, the last quarter-to-quarter increase was a miniscule 0.3% one in Q2 of 2011. It looks as if growth tends to regularly occur in Samsung’s second quarter.

Last quarter’s revenue growth helps to debunk rumors that Samsung was Continue reading “Samsung Revenues Reflect NAND Price Increase”

Alternative Memory Technologies Patiently Wait For Market to Explode

Lane Mason of Objective Analysis recently shared with The Memory Guy an article he wrote for the 4 April 2007 Denali Memory Report covering Phase Change Memory (PCM or PRAM.) It looked like something big was about to happen with the technology: PCM looked nearly ready to enter production.

The article included an excerpt of an EE Times interview with Micron’s CEO, the late Steve Appleton, in which Appleton stated that PCM advocates threatened to take over the memory market in 2000.

Here it is 2012, and PCM represents little more than a drop in the bucket when it comes to memory sales, although Continue reading “Alternative Memory Technologies Patiently Wait For Market to Explode”

Samsung DRAMs in Massive Leibniz SuperMUC

Today Samsung announced that its chips are used exclusively to make up the 324-terabytes of DRAM in Germany’s new Leibniz Supercomputing Centre SuperMUC supercomputer.

Samsung’s release tells us that the SuperMUC, the most powerful supercomputer system in Europe, is an IBM System x iDataPlex dx360 M4 server built using over 18,000 Intel Xeon CPUs and over 80,000 4GB DRAM modules from Samsung. (Simple math makes this out to be 82,944 modules.)

That looks like a lot of silicon! Let’s see how much that might be.

A 4GB parity DRAM module would use nine 4Gb DRAM chips, which Samsung appears to Continue reading “Samsung DRAMs in Massive Leibniz SuperMUC”

Toshiba to Cut NAND Production by 30%

In a surprise announcement Toshiba has said that it will immediately cut NAND flash production by approximately 30%. The company explains that this is being done “to reduce inventory in the market and improve the overall balance between supply and demand.” Toshiba’s release implies that this move is expected to improve prices, which have dropped as low as $0.31/GB recently.

By common measures of market share, which typically leave out SanDisk (for reasons too complex to discuss here) Toshiba holds a share of roughly 30% of the NAND flash market. By cutting its output by 30% Toshiba would be reducing overall NAND supply by 10%. If we were to include SanDisk, then that percentage would decrease to about 7.5%. Either one of these is significantly more than Continue reading “Toshiba to Cut NAND Production by 30%”

Micron PCM Enters Mass Production

After years of prototyping Micron Technology claims to be the first to introduce production volumes of Phase-Change Memory, or PCM. This memory, also known as PRAM, has long been positioned as a contender to replace flash once flash reaches its scaling limit. Rather than use electrons to store a bit, PCM uses a type of glass that is conductive when in a crystalline state and resistive when amorphous, two states that are relatively easy to control. The size of the bits can shrink to a very small dimensions, allowing PCM to scale into the single-digit number of nanometers, which most folks today believe to be beyond the realm of flash.

This product began its life at Intel, then followed the Numonyx spin-off, and was taken over by Micron when it acquired Numonyx. In fact, Intel got into PCM very early on – this post’s graphic is the cover of an Electronics Magazine from September 1970 with an Intel story, written by Gordon Moore, telling about a 128-bit PCM research chip.

So far only three companies have produced samples Continue reading “Micron PCM Enters Mass Production”

NAND Flash at 35 Cents per Gigabyte

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 “NAND Flash at 35 Cents per Gigabyte”

DensBits – Making TLC Act Like MLC

DensBits, an Israeli start-up, has introduced a new technology and a new product today. The company’s new eMMC controller, the DB3610, embodies DensBits’ “Memory Modem” technology, which is a blend of ECC, DSP, and flash management that the company says can give TLC flash endurance superior to that of MLC flash with performance nearly as good as competing controllers can provide with MLC.

That’s a big claim!

DensBits’ Memory Modem views NAND flash as a noisy communications channel, using those algorithms developed to support deep Continue reading “DensBits – Making TLC Act Like MLC”

How Cheap is Flash?

The Memory Guy was a little surprised to see the advertisement in this post’s graphic. It was from an April 8 newspaper ad for Fry’s Electronics.

It’s a little early to see NAND selling for this little: The original price of $21.99 for a 32GB USB flash drive comes to $0.69/GB, and the price after the rebate of $16.99 means that the price per gigabyte of the flash is only $0.53!

At the time the lowest spot market pricing for MLC flash on the InSpectrum spot price website was $0.53, and $0.47 for TLC. According to DRAMeXchange MLC is selling for as little as $0.48.

That’s not a lot of margin for Patriot or Fry’s when you add in the cost of t Continue reading “How Cheap is Flash?”

NAND Flash Turns 25!

On April 3 Toshiba celebrated the 25th anniversary of NAND flash. The technology, developed by Toshiba researcher Fujio Masuoka, was not expected to succeed, as explained in Eli Harrari’s keynote for ISSCC in February.

Toshiba said in a release that the company’s “commemoration of the 25th anniversary of the invention of NAND flash will continue throughout 2012,” and will include “notable industry events and consumer participation.”

There is certainly reason to celebrate. This technology has grown faster than any semiconductor market in history, Continue reading “NAND Flash Turns 25!”
