Programmable and gates basically means that you connect whatever inputs to the and gates that you need.  For example if you need ABC' , AB'C , and ABC, all the chip does is make these connections.  In a PLA, both the OR gates and the AND gates can have their inputs connected and disconnected.  In a PAL, only the AND gates can have their inputs connected and disconnected("programmed")

Hi Jasneet
Both PLA and PAL has array of and, or gates with programmable interconnects.

The difference is

PLA has both and and or gates in programmable format whereas PAL(easy to remember as Prog And Logic) has only and gates programmable i.e or gates are fixed.
