Yes, but they do pixel-binning in most cases (a final pixel is the average of 4 pixels from the sensor), so your real image is 10-12Mpix.
Anyway, since processing is done on 32-bit FP values (4 bytes per channel), when you have a 25MP layer to process one color channel you need 100MB, and if the channels are not processed independently you need 300-400MB, so RAM gets used pretty quickly.
