Even though we all know that reducing power consumption in NAND Flash Storage is a good idea, it is worthwhile to take a deeper dive into the underlying reasons for this. A white paper by Hyperstone, a leading developer of Flash controllers, discusses these topics providing useful insight into the problem and its solutions. The … Read More
In order to beat Moore’s Law NAND Flash memories have moved from a planar topology to 3D construction. This allows for increased memory sized in much the same way a multistory building provides more building square footage on the same size building lot. Just like in building construction, adding a third dimension to the mix increases… Read More
Flash memory has become ubiquitous, so much so that it is easy to forget what life before it was like. Large scale non-volatile storage was limited spinning disks, which were bulky, power hungry and unreliable. With NAND Flash, we have become used to carrying many gigabytes around with us all the time in the form of cell phones, USB… Read More
On the Sunday evening at IEDM last year, TechInsights held a reception in which Arabinda Das and Jeongdong Choe gave presentations that attracted a roomful of conference attendees. Arabinda was first up, giving a talk on the “10-year Journey of Apple’s iPhone and Innovations in Semiconductor Technology”, followed by Jeongdong… Read More
I’d wager that if I mention autonomous vehicles, the first thing that you would think of would be autonomous cars. The truth is that we will see many other kinds autonomous vehicles in the years ahead. Their applications will range from package delivery to saving lives on the battlefield. Of course, to some extent they are already… Read More
The move to SSD storage for enterprise use brings with it the need for difficult to design enterprise capable SSD controller SOC’s. The benefits of SSD in hyperscale data centers are clear. SSD’s offer higher reliability due to the elimination of moving parts. They have a smaller foot print, use less power and offer much better performance.… Read More
You may know that up until now NAND flash has been a planar technology. But just as with SoC processes where we have had to go vertical to FinFETs, NAND flash has reached the limitations of scaling in the 20nm nodes and is also going vertical. It is not just a lithography issue but there are also reliability and voltage scaling issues.… Read More
There are many facets of our lives that are being driven to a more virtual method of doing things. This is largely due to issues such as scaling due to whatever reason – technical, business, economic. Let’s look at some general cases: In yesteryears people used to travel all the way for face-to-face meetings; today virtual meetings… Read More
In the beginning of this decade there was a lot of buzz around 3D chip manufacturing. Many EDA tools were developed to facilitate semiconductor designs in 3D space. Naturally, we are moving to the edge on 2D without much room to further squeeze transistors and interconnect. However, lately I haven’t heard much about 3D products.… Read More
The press release about ONFI 3.0 support was launched by Cadence at the beginning of this year. It was a good illustration of Denali, then Cadence, long term commitment to Nand Flash Controller IP support. The ONFI 3 specification simplifies the design of high-performance computing platforms, such as solid state drives and enterprise… Read More
