How to recreate this particular synth sound.

I'm wondering how to recreate this particular synth sound found in the two songs below. If someone could also tell me the "generic" name of this sound, it would be very helpful.



Ludacris - Party Girls - 1:02 http://ift.tt/1wycddv

Nosaj Thing - Tell - 0:27 http://ift.tt/1vqdNS1
