How many external memory controllers can an FPGA have?

[nervecell_23]

To have a large external memory bandwidth, can I instantiate any number of external memory controllers as long as there is enough hardware resource?

Is external memory only connected to dedicated I/O pins in a FPGA? or any pins can be used by the memory controller to connect to an external memory?

That's a vague question, so you're going to get a vague answer: it depends. You don't specify the FPGA or the type of memory.

Some FPGAs have dedicated memory controllers and/or pins; some don't.
