I'm not sure what the first 2 in your configuration means because I've never seen something like that before (2 sticks maybe?), but from what I understand, 32Mx64 simply means that you have a 256MB module (32 x 64 = 2048 Mbits = 256 Mbytes). From that information, I don't believe there is any way to tell if the RAM has 8 or 16 chips. You would need the chip density for that.
