This is one of the big improvements that Nikon has over Sony and also why Nikon in recent years have gone over their 12mp limit that they had up until about 6ish years ago. One of the reasons they have gone over that is because of noise cancellation algorithms.

And the low noise of the Sony sensors at high ISO.
Sony bought out some company to get the Exmor tech which is basically having the analogue to digital converters actually on the sensor not a separate circuit board like on Canon. The longer the distance the signal has to travel the higher the noise and this is one big area where the Sony gets ahead with low noise in dim areas.
Sony also has a patent sharing agreement with Optina who have many patents in CMOS sensors. One of which is showing up in the latest Sony A7s where the ISO noise level drops a few times as you go up the ISO levels as it changes a gain factor in 2 places. This increases the dynamic range. Not massively but every bit gained is valuable.
