... DDR SDRAM modules use internally configured quad-bank DDR SDRAM devices. DDR SDRAM modules use a double data rate archi- tecture to achieve high-speed operation. Double data rate architecture is essentially a 2n-prefetch architec- ture with an interface designed to transfer two data words per clock cycle at the I/O pins ...
