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

That is completely dependent on the ASIC libraries. In FPGA you are out of
luck with higer amount of ports that are available in some ASIC libraries.
For example in the ASIC library I use there are: single port, 1 read 1 write,
dual port and 4-port memories. And then different versions of those
(density, power, speed).
