Default SDRAM interface through FPGA. How do I ensure no mis-commands?

For example, during the refresh time, a new command arrives from the other
modules,
and causes the refresh time to be shortened, what will happen to the memory?

Hi <anoynmous poster>,

I'm not sure how others have done it, but in the past, I've given
priority to read or write commands over that of a "request" for
refresh. My refresh timer was conservative such that it wouldn't
matter if a refresh was pushed back by a few cycles.
