Sony announces the development of the industry's first 3-layer stacked CMOS sensor with DRAM for smartphones. The new 20MP 1/2.3-inch sensor minimizes the rolling shutter distortions by providing a 8.33ms-fast readout of the full 20MP of the sensor into the internal 1Gb DRAM.
The high-speed readout capability makes it possible to record up to 1,000 fps (approximately 8x faster than conventional Sony products) super slow motion movies in full HD (1920x1080 pixels).
Sony also publishes a Youtube video showing the new sensor capabilities:
Sony has presented the new sensor at ISSCC 2017. Few slides from the demo session:
Update: A slide on one of the high speed modes added below. There are 4 ADCs per column in order to read 4 rows in parallel and a SF coupled binning:
