The latency of accessing physical memory is asymptotically a function of N for sufficiently large N - ie. big enough that signal propagation delay to the storage element becomes a noticeable factor. This is not generally relevant for PCs because the distance between cells in the DIMM does not affect timing; ie. the memory is timed based on worst-case delay.
