The basic structure of Dynamic RAM has not changed, it still takes about 50nS for row precharge (Tras
and 20bS column reads. All they've done is speed up the interface logic. The memory cell access is no faster.
OK, so once you've opened a row, you can read that faster, but how many operating systems are
optimized to keep the data row aligned in the system memory? You have a data request that is outside
of the row you've opened, you have to close that row and open another, 120nS penalty.
At 1.0GHz, that's 120 clock cycles.
