6.3.6 Data Write (MD[63:0])
The load on the data signals is much lower than
the address/control signals for an unbuffered
DIMM. For a registered DIMM the data signals are
the only memory pins of the DIMM which are not
registered. For the design to get maximum benefit
from using registered DIMMs the timings should
be compared to the timings for registered DIMMs
for the other pins.
6.3.7 Data Read (MD[63:0])
The data read simulation circuit is shown below..
