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”
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 “Why DRAMs are Like Steel”
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?”
SK Hynix and Spansion have announced a strategic NAND alliance under which Hynix will serve as a foundry for low-density SLC NAND chips made for Spansion using Hynix’ advanced processing nodes.
These products, aimed at the embedded market, should serve to strengthen Spansion in a market in which the company thrives. In fact, Spansion expressed this very well in their press release, citing: “Spansion’s recognized customer support and commitment for longevity of supply, which is highly valued in the embedded market, where Spansion has established relationships.”
The new chips will be manufactured in “4x, 3x, and 2xnm” process technologies.
The companies have also agreed to cross-license their patent portfolios.
You may be asking yourself: “What does Hynix Continue reading “Hynix and Spansion Join Forces”
For months rumors have abounded regarding Elpida’s viability and plans the company has to overcome its current financial woes. Although the company has been questioned about advanced payments and loans from its customers, takeover and merger possibilities, and even government intervention, Elpida has remained silent, refusing to comment.
Today the company finally made a statement that it will be adding a note to its Q3 results and earnings report: “on Matters concerning the Assumed Going Concern.”
This statement, which looks like it was written very carefully by either Continue reading “Elpida Finally Makes Statement”
Hynix Semiconductor has a new name. Through SK Telecom’s November 2011 purchase of 21.1% of Hynix’ shares from its creditors mobile phone service provider SK has acquired controlling interest of the company and is re-branding Hynix as SK-Hynix.
The Memory Guy has not discussed this with either Hynix or SK Telecom so far, but it seems unusual that a 21.1% stake in a company would gain a controlling interest.
Suffice it to say that Hynix’ creditor banks, who have been trying to divest themselves of their ownership of Hynix for a few years, have finally found Continue reading “Hynix is now SK-Hynix”
Rambus announced that the company has acquired privately-held Unity Semiconductor, an alternative memory technology company for $35 million. Unity employees have joined Rambus and will continue to develop next-generation nonvolatile memory.
Unity has an interesting technology that has caught the eye of some leading memory firms, including Micron, who had an exclusive right to Unity’s technology. The company’s CMOx is based on oxygen ions moving within a semiconducting material. It’s one species of resistive RAM.
Although Unity has been trying for years to manufacture very high density nonvolatile memory chips, The Memory Guy is not aware that the company has yet produced the chips they have set out to make.

The current battle between Cypress Semiconductor and GSI Technology caught The Memory Guy’s eye recently. Many readers may have missed this battle that commenced when Cypress filed a Federal Trade Commission (FTC) lawsuit in the US in which the company asked for GSI SRAMs to be barred from importation into the US because of a patent dispute.
GSI has issued a countersuit with a complaint of anticompetitive practices.
What garnered my interest is how similar the tactics in this lawsuit are to those used for some of the Rambus lawsuits that evolved over the years: Continue reading “Cypress vs. GSI Battle Following Rambus Lead”
