For an SRAM you are right that you shouldn't use the ALTMEMPHY function.

If you are using SOPC Builder/QSys, you should add a tristate bridge and create a component with a tristate avalon slave interface to add the SRAM to your system.

If you aren't using SOPC Bulider or QSys then you'll have to write your own controller but it's very easy with an SRAM.
