what's different of LAB, ALUT, etc?

Who can tell the difference of LAB, ALUT, Logic Cell(LC), LCCOMB and LCFF? I'm always confused by these concepts. Thanks.

yes combinatorial decisions are made through luts. There are practically no isolated and/or/nor etc gates fabricated separately as we know them.

A lut can implement logic readily. e.g 4 bit lut(1 bit x 4) can be addressed by 2 bit input and the 4 bit contents set to required function at configuration.
