Paul, I read somewhere that by changing the aspect ratio of memory cell capacitors they have the requisite amount of capacitance but take a smaller amount of real estate. Going from .25 to .18 halves the area and all other things equal will double the density of the memory laid out. If, in addition, the cells can be made smaller but deeper(of course I speak of the charge storage capacitor for the memory cell, that which holds the charge which is refreshed with dynamic ram, static does not have this, the strictly surface based features like lines etc are not affected.
