i think it is not SI or EMI issue.
if you can layout it as 1inch, SI and EMI is OK.

Hi experts,
As we know, there are two kinds of applications for DDR, one is SDRAM on
board, and another is DIMM. In the most of routing guide for DIMM, there is
min trace length requirement, e.g. more than 2inch or 1inch, but there is
no same requirement for SDRAM. Why?
