One of the biggest developments taking place in the semiconductor industry is the emergence of 3D NAND memory technology. Products are available today that feature 3D NAND devices. It has taken years to become a reality — since Toshiba first discussed the concept of 3D NAND at the VLSI Symposium in 2007 – and now it is poised to replace planar NAND flash memory for storage.
The path that has led to this point is similar to what happened with the logic roadmap; despite innovative workarounds, the era of traditional planar "shrinks" for NAND is running out of steam. And, just as with logic, it has required significant technical advances to overcome the formidable challenges to successfully manufacture complex vertical 3D NAND designs.
What’s the population of Singapore? How many species of salmon are there in the world? Who won the gold medal for men’s downhill skiing in the 1994 Olympic Winter Games? Answers to these questions along with an infinite amount of other information are now easily available to a majority of the world’s fingertips thanks to something that happened 44 years ago today. That’s when two computers, one at UCLA and one at the Stanford Research Institute, connected over ARPANET (Advanced Research Projects Agency Network) to exchange the world’s first “host-to-host” message. This rather inauspicious event is viewed by many as the birth of a technology that became a communication tool now used by billions of people around the world every day. Of course, I’m talking about the Internet.
