Default Re: How do I make dual-port RAM from single port RAM?

That is a clever solution that I hadn't thought of. Of course, your
VALID_BIT array needs the capabilities of a true dual-port memory. So
this doesn't really build a dual-port memory just out of RAMs. It
builds it from 4 RAMs and a smaller dual-port memory (just as many
elements, but only 1 bit wide). You would have to build that smaller
dual-port memory out of flip-flops. The result still might be smaller
than building the full-size memory out of flip-flops.
