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
