From The Free On-line Dictionary of Computing (30 December 2018) :

  Programmable Array Logic
      (PAL) A family of fuse-programmable logic
     integrated circuits originally developed by MMI.
     Registered or combinatorial output functions are modelled in
     a sum of products form.  Each output is a sum (logical or)
     of a fixed number of products (logical and) of the input
     signals.  This structure is well suited for automatic
     generation of programming patterns by logic compilers.
     PAL devices are programmed by blowing the fuses permanently
     using overvoltage.
     Today, more complex devices based on the same original
     architecture are available (CPLD's for Complex PLD's) that
     incorporate the equivalent of several original PAL chips.  PAL
     chips are, however, still popular due to their high speed.
     Generic Array Logic devices are reprogrammable and contain
     more logic gates.
