I don't think there are any.  I presume the DRAM is organized as 512Kx8.
512K = 2^19 and 19/2 is not an integer.  Since the RAM is organized in a
square matrix (on all DRAM's I know of), the 512Kx8 will be organized as
two 2^9 by 2^9 matrixes.  The two CAS lines select between the two
matrixes.  An 8MBit DRAM will again have only one CAS line since it would
organized as one 2^10 by 2^10 matrix - giving 1024Kx8.

Anyway, that's the way I think it is ;-)
