The DP8400 DRAM interface family provides complete solu- tions to memory support. This begins with the LSI functions such as the DP8400 expandable error checker/corrector and the DP8409A DRAM controller/driver. It continues with the DP84240 and the DP84244 high performance buffer/ drivers. Finally, it concludes with easy interface to popular microprocessors with the use of the DP84XX2 series. It is the first family of DRAM support circuits designed

for universal applications with multiple microprocessors, with no manufacturers CPU enjoying a favorite role.

Data sheets and more detailed application information are available for all the members of the DP8400 family. Contact your local National Semiconductor representative or Nation- al Semiconductor directly.
