Read the full press release at Samsung:

The new CIS chip provides a high signal to noise ratio (SNR), a key measure of overall image quality. Samsung achieved the high-resolution level by implementing advanced light sensing features and minimized noise levels.  Notably, an extended photo diode technology was implemented to achieve higher light sensitivity and saturation levels, resulting in an enhanced fill factor.

Furthermore, it provides the same image quality as the charge-coupled device (CCD) image sensors currently used in most digital cameras and camcorders. Since the new CIS only uses one-tenth the power of a CCD image sensor, it should quickly replace CCDs in all three key applications—mobile phones, digital cameras and camcorders.
