It is an interesting question but I think the parent poster did not mean density in the pure physical sense.
That is more memory but less mass which is not physical density. Also I am not sure if gamma rays need to just hit the physical bits to mess things up. If is the case where other things can be hit then it seems surface area might have high correlation but probably not.
I don't know what the answer is but I would imagine that the error rate would be the same percentage assuming orientation is kept the same.
Of course if you are going at extreme macro sense (think Asimov last question computers [1]) then density absolutely probably plays role as gravity starts to cause enormous amount of collisions. This actually happens in stars and is why photons take a long time to escape from the star as well as the edge of black holes where collisions are happening extremely frequently.
