EXTERNAL MEMORY CONFIGURATIONS
The DDR SDRAM interface of the sequential flow-control (SFC) device has
a 64-bit output data bus that provides up to four (16-bit SDRAM) external DDR
SDRAM connections. For multiple memory connections, they must be of the
same density configuration and speed grade. For example, two device
connected cannot consist of one 128Mb and one 256Mb memory nor two
128Mb with one at 133MHz and the other at 166MHz. Below is a summary of
thepossibleconfigurations:
One 16-bit device connecting a x16 interface to the DDR SDRAM
One 32-bit device connecting a x32 interface to the DDR SDRAM
Two 16-bit devices connecting a x32 interface to the DDR SDRAM
Two 32-bit devices connecting a x36 interface to the DDR SDRAM
Two 32-bit devices connecting a x64 interface to the DDR SDRAM
Three 16-bit devices connecting a x36 interface to the DDR SDRAM
Four 16-bit devices connecting a x64 interface to the DDR SDRAM
These various configurations determine the storage density of the SFC
device. Thestoragedensitycanrangefromaminimumof128Mbtoamaximum
of 1Gb. Table 3 lists the possible ways to connect the DDR SDRAMs and the
number of chipset solutions to obtain the various storage densities.
NOTES:
1. The chip solution number includes the sequential flow-control device and external DDR SDRAM
