reading and writing to the same address usually isnt possible in the same cycle, or if it is, you have to use the ram asynchronously which Im not sure is possible with all devices. Using it asynchronously will reduce your FMAx.

If you are reading and writing, usually you read in 1 clock, and write back in the next (while simultaneously reading the next address).
