GALS and PALS

[Chasse]

Can anyone tell me and its more just out of interest at the moment.

I asked previously..

Onece a GAL has been programmed can it be duplicated ?

Or is what has been suggested to me about the chip self destructing by tying
data lines to 5v correct.

And I have a GAL and a PAL on two copies of the same electronic item I
understand that the GAL may be protected but can the PAL be copied ?

Just Curious.

There is almost always an option to either protect or leave accessible the
programming information after the device (PAL or GAL) is programmed.
