CONNECTING THE DDR SDRAM
Below are the various chipset solution configurations available to the
sequential flow-control device (see Figure 2a-2g). The external memory
interface is designed to seamlessly connect one or more DDR SDRAMs. The
output signal names should be connected directly to its corresponding input
signal on the DDR SDRAM. There are three signals on the DDR SDRAM that
mustbetiedtoastaticstate.CKE,
CS,andDM.Table4outlineshowtoconnect
the many interface pins to the DDR SDRAM(s). Figure 3 and 4 are some
examples of the memory interface connections for various density configura-
tions. For information on DDR SDRAM layout recommendations, please see
IDT application note AN-423.
