Breakthrough new Sony sensor adds DRAM: Speeds up frame rates by a factor of 4!

Sony is threatening to again up the ante for smartphone cameras. Building on its history of stacked sensor development, it has unveiled a new CMOS sensor that adds a third layer – of DRAM – between the photo sites and the circuitry. The result is a massive improvement in readout speed and frame rate, making all sorts of features possible, and greatly reducing the problem caused by rolling shutter artifacts. You can .
