Block vs Distributed RAM

Thanks thepancake,

As kaz reply "distributed ram makes use of (some) luts of logic fabric as memory instead of implementing them for logic. these are good for multiple small blocks(fine grain). e.g. 3 input lut can provides 8 1 bit locations."

1) So how can u says that Cyclone IV family does not have distributed RAM ?

2) Is there any Cyclone FPGA which has Distributed RAM , also how to configure LUT as distributd RAM ?

3) so Whenever an FPGA is configured , is it actually program this block RAM only ?
