Thank you for your answer. 

How to connect two FPGA board, especially over GPIO interface

Just connect the pins together and implement your own transfer protocol, or use something like a UART. 

If you need more help you'll have to give more details. Which boards? To transfer what? What speed? Over what distance?

Thank you for your answer. 

I have two Altera De2 boards. I want to use the M4K memory blocks of slave board.

You can probably use the 40-pin expansion headers and put wires between the two boards. Have a look at the board schematics to check what pins you can use. 

As for accessing the memory blocs, then you'll probably have to design your own protocol.
