Intel and Micron Technology on Tuesday unveiled what they touted as a new kind of memory chip that could “revolutionize” computing devices, services and applications.
Intel and Micron have a new way to store data that they say is denser, tougher, and faster than the competition, and it’s already starting production. In a live keynote today, the companies announced 3D Xpoint, a new category of non-volatile memory that claims to be 1,000 times faster than the NAND architecture underlying most flash memory cards and solid state drives. The new architecture does without transistors entirely, relying on a bulk material property change to switch bits from a low-resistance to a high-resistance state. From there, memory cells are layered in an intricate three-dimensional checkerboard pattern that Intel researchers say is 10 times denser than conventional memory.
UT Dallas scientists have constructed novel fibers by wrapping sheets of tiny carbon nanotubes to form a sheath around a long rubber core. This illustration shows complex two-dimensional buckling, shown in yellow, of the carbon nanotube sheath/rubber-core fiber. The buckling results in a conductive fiber with super elasticity and novel electronic properties. (credit: UT Dallas Alan G. MacDiarmid Nanotech Institute)
An international research team based at The University of Texas at Dallas has made electrically conducting fibers that can be reversibly stretched to more than 14 times their initial length and whose electrical conductivity increases 200-fold when stretched.
UC Berkeley engineers, in collaboration with colleagues at Taiwan’s National Chiao Tung University, have developed a 3D printing process for creating basic electronic components, such as resistors, inductors, capacitors, and integrated wireless electrical sensing systems.
SSDs and other flash memory devices will soon get cheaper and larger thanks to big announcements from Toshiba and Intel. Both companies revealed new “3D NAND” memory chips that are stacked in layers to pack in more data, unlike single-plane chips currently used. Toshiba said that it’s created the world’s first 48-layer NAND, yielding a 16GB chip with boosted speeds and reliability. The Japanese company invented flash memory in the first place and has the smallest NAND cells in the world at 15nm. Toshiba is now giving manufacturers engineering samples, but products using the new chips won’t arrive for another year or so.
After 85 years of searching, researchers have confirmed the existence of a massless particle called the Weyl fermion for the first time ever. With the unique ability to behave as both matter and anti-matter inside a crystal, this strange particle can create electrons that have no mass.
The SCiO is the world’s first spectrometer that fits in a pocket, and it can measure the molecular fingerprint of just about anything you see.
“An analysis of the history of technology shows that technological change is exponential, contrary to the common-sense “intuitive linear” view. So we won’t experience 100 years of progress in the 21st century — it will be more like 20,000 years of progress (at today’s rate). The “returns,” such as chip speed and cost-effectiveness, also increase exponentially. There’s even exponential growth in the rate of exponential growth. Within a few decades, machine intelligence will surpass human intelligence, leading to The Singularity — technological change so rapid and profound it represents a rupture in the fabric of human history. The implications include the merger of biological and nonbiological intelligence, immortal software-based humans, and ultra-high levels of intelligence that expand outward in the universe at the speed of light.” — Ray Kurzweil.
Two separate teams of researchers have found evidence for a theorized type of massless particle known as a “Weyl fermion.” The discovery was made by scientists at Princeton University in New Jersey and the Massachusetts Institute of Technology, and could herald a whole new age of better electronics.
Scientists have discovered Weyl fermions, elusive massless particles theorized 85 years ago that could give rise to faster and more efficient electronics because of their unusual ability to behave as matter and antimatter inside a crystal.
