In a move touted as a merger of equals, Cypress will acquire Spansion in an all-stock transaction slated to close in the second quarter of 2015. The purchase price is estimated at $1.6 billion.
Cypress points out that it is the leading producer of SRAMs, and that Spansion is the leading NOR flash provider.
One striking feature of this transaction is the Continue reading
SanDisk co-founder Eli Harari was awarded the National Medal of Technology and Innovation on November 20 by President Obama. The medal, which was bestowed upon Dr. Harari in a White House ceremony, is the United States’ highest honor for scientific and technological achievement, and recognizes those whose lasting contributions have created a greater understanding of the world and improved the lives of many.
Harari co-founded SanDisk more that 25 years ago with the vision that flash memory would be used to store data in mobile products, a vision that initially took seed in photography in the 1990s, and has since become the fastest-growing Continue reading
An article in a recent issue of Business Korea posits that Apple may be having trouble stemming from the company’s adoption of TLC flash in it’s new iPhone 6.
The article states:
considering that technical defects mainly occur in the 128GB version of the iPhone 6 Plus, there might be a problem in the controller IC of triple-level cell (TLC) NAND flash.
The problem has led to numerous warranty replacements and the looming prospects of a recall.
(Note that Continue reading
For those who were unable to attend the Flash Memory Summit, Samsung’s Senior VP of Memory R&D, Bob Brennan, announced in his keynote speech that a 3D 32-layer V-NAND, a chip that would achieve twice the chip density of planar NAND, was entering production and that SSDs would follow in a month. Now, two months later, Samsung has announced those SSDs.
This week’s release reiterates Continue reading
Wiley has recently published a new book by Betty Prince titled Vertical 3D NAND Technologies that is one to consider if you want to bring yourself up to speed on recent research behind today’s and tomorrow’s 3D memory technologies.
For those who haven’t previously encountered Dr. Prince, she is the author of a number of key books covering memory design and holds memory patents written over her 30-year career in the field.
The book provides capsule summaries of over 360 papers and articles from scholarly journals on the subject of 3D memories, including DRAM, NAND flash, and stacked chips.
These papers are organized into Continue reading
Although the course was very well received, I never posted a link to it on The Memory Guy blog. This post is intended to correct that error.
The course runs 75 minutes and covers the basics of DRAM, non-volatile RAM, SRAM, NAND flash, NOR flash, mask ROM, and EEPROM. It explains each technology’s advances in size, cost and performance, leading up to the development of Continue reading
SanDisk has introduced an SD Card with a whopping 512 gigabytes of storage. Noting that SD Card capacities have increased by 1,000 times over the past ten years, from 512MB to 512GB, the company says that this product is aimed at professional HD videographers (who can justify its $800 price) allowing them to shoot Raw-format footage without shutting their cameras off, which could potentially allow them to miss a magic moment.
To The Memory Guy this represents an amazing piece of packaging technology. Let’s see why:
In 2003 SanDisk’s 512MB card contained Continue reading
One of the more fun aspects of last week’s Flash Memory Summit was the presentation of the Lifetime Achievement Award. This is something that the show’s management has allowed me to do for the past four events.
This year’s award went to Dr. Simon Sze, who co-invented the floating gate transistor (the basis for all flash, EEPROM, and EPROM) at Bell Labs back in 1967.
Sze and his partner Dawon Kahng were finishing lunch in the company cafeteria with a cheesecake dessert. The two discussed what would happen if a MOSFET was built with extra layers like the layers in the cake. Their intent was to use semiconductors to replace Continue reading
Long-term clients of mine, even those dating back to my decade at Dataquest in the 1990s, are familiar with the concept that spot prices behave differently during a shortage. When there is too much DRAM spot prices remain below contract prices, because OEMs who bought too much product clear their inventory at quarter end (and other times) by selling at a loss.
During a shortage the opposite is true: OEMS find that they can’t get as much DRAM as they wanted through their contract sources, so they shop for the balance on the spot market. Since there are more buyers than sellers, spot prices invariably raise higher than contract prices.
When the prices change from one state of affairs to the other then it is safe to assume that Continue reading
