Researchers built the prototype device using bismuth ferrite. In conventional computer memory, information is stored in cells that hold different amounts of electric charge, each representing a binary '1' or '0.' Bismuth ferrite, by contrast, and can represent those binary digits, or bits, as one of two polarization states, and, because of its photovoltaic properties, can switch between these states in response to visible light."
An anonymous reader writes "The PC market (desktops, notebooks, and tablets) is expected to see almost half a billion units ship this year, 493.1 million to be exact, representing 7 percent year-on-year growth. Unsurprisingly, the key driver behind this growth will be tablets, accounting for 37 percent of the overall market and seeing 59 percent growth to 182.5 million units. The latest estimates come from Canalys, an independent analyst firm. Nevertheless, it's worth emphasizing that these are estimates, though they do line up with what the broader industry is seeing: desktops are down, laptops are down, but tablets are up."
