Samsung publishes an interview with Galaxy S9 fast camera design team:
"We were able to achieve a readout speed that is four times faster than conventional cameras thanks to a three-layer stacked image sensor that includes the CMOS image sensor itself, a fast readout circuit, and a dedicated dynamic random-access (DRAM) memory chip, which previously was not added to image sensors,” explained Dongsoo Kim. “Integrating DRAM allowed us to overcome obstacles such as speed limits between the sensor and application processor (AP) in a high-speed camera with 960fps features.
“It wasn’t easy testing out Motion Detection for Super Slow-mo, especially with people staring at us when we brought our laptops to these amusement parks and took videos of fast-moving rides. However, we were all committed to getting the feature exactly right,” said Dongsoo Kim.
“We also shot for two hours in the middle of a mountain range, on a freezing night, to complete the low-light camera function,” recalled Sungwook Choi."
Samsung also publishes a picture showing the 3-Layer structure - pixel layer on top, logic layer in the middle and DRAM on the bottom:
