The module uses internally configured quad-bank DDR2 SDRAM devices. The module uses double data rate architecture to achieve high-speed operation. DDR2 SDRAM modules operate from a differential clock (CK and CK#). READ and WRITE accesses to a DDR2 SDRAM module is burst-oriented; accesses start at a selected location and continue for a programmed number of locations in a programmed sequence. The burst length is either four or eight locations. An auto precharge function can be enabled to provide a self-timed row precharge that is initiated at the end of a burst access. The DDR2 SDRAM devices have a multibank architecture which allows a concurrent operation that is providing a high effective bandwidth. A self refresh mode is provided and a power-saving “power-down” mode. All inputs and all full drive-strength outputs are SSTL_18 compatible. The DDR2 SDRAM mod.
