Does anyone know how much memory is available on board to each design for the tiny tapeout project? If each project could include something like a FPGA Block RAM I feel the project would have (much greater) utility and flexibility. Although I understand that might not be possible.

You have to make your own, some people have SRAM compilers - depending on how big a tile you choose the more memory you get (it's going to be in the 100s to low 1000s of bits)
