Hi,
You can use any free port on the MCU, for example Port B, to connect 8x data lines D0-D7. Then you would need another port to connect control lines such as chip enable, R/W select etc.
Anyway, here is an older post which should be of interest. Please, check all the links, especially the one in the last response.
