Sony shows off 3-layer stacked smartphone image sensor that can shoot 1000 fps at 1080p

Sony has today announced the development of a 3-layer stacked CMOS image sensor with DRAM for smartphones, making it possible to capture video at 1000 fps. The new chip comes with a DRAM layer in addition to the conventional 2-layer stacked CMOS structure with a back-illuminated layer of photo-sites and a circuit layer for signal processing. The DRAM acts as a temporary buffer for image data that is recorded at very high speeds, before it is put out at normal speed to a conventional image signal...
