***Info:
The SL9351 Memory Controller supports  PC/ AT systems based on Intel's
80386DX microprocessor. It  is a member of VIA's  FlexSet family which
utilizes the same  core logic across the entire  PC/ AT spectrum.  The
SL9351 is backward compatible with existing memory controllers for the
80386DX (SL9350).  Boards designed using  the SL9350 can be  used with
the new SL9351 without modifications  and with existing BIOS. In order
to  take advantage  of the  SL9351's many  new  programmable features,
minor board modification and a  modified BIOS is required for enhanced
performance.

The SL9351  offers the advanced memory control  functions and features
needed  to  develop high  performance  PC/  AT  systems without  using
external TTL  Logic. The SL9351 supports two-way  page interleave mode
for 80386DX based  designs. The Page interleave option  can be enabled
or disabled using the  configuration registers. All memory banks which
are interleaved use the same type of memory.  Designers can enable the
staggered RAS option during refresh, which minimizes power surge. Both
pipeline and non-pipeline modes are supported by enabling or disabling
the next address controls, and providing ready at the correct time.
